**Educational activities**

Courses created at U of C

- ENME 547: The finite element method in Engineering. This course was established in 1985 to address the then growing demand for mechanical engineers with a solid background in the finite element method and its applications. The course has been taught ever since as a 4-th year undergraduate technical elective, and occasionally as a graduate course.
- ENME 653: Continuum Mechanics. Established ca. 1990, this graduate course has attracted students from several departments, including Mechanical, Civil, Chemical and Petroleum Engineering, Kinesiology, and Geophysics. It is still being taught to this day.
- LATI 205 and LATI 207: The Latin of Science. Established in the Fall of 1999, these two popular courses, that draw undergraduate students from Engineering, Sciences and the Humanities, are being successfully taught and keep attracting students from varied backgrounds.

Courses taught over the years (listed only those taught more than 10 times)

- ENGG 202: Engineering Statics
- ENGG 317: Mechanics of Solids
- ENGG 349: Dynamics
- ENME473: Fundamentals of Kinematics and Dynamics of Machines
- ENME470: Mechanics of Deformable Solids II
- ENME 547: Finite Element Method
- ENME 633: Mathematical Techniques for Engineers
- ENME 653: Advanced Continuum Mechanics
- LATI 205: The Latin of Science I
- LATI 207: The Latin of Science II

Educational initiatives

- The `Galileo Program’. Proposed first in 1992, this initiative advocated the fully-fledged development of an Honours Engineering Science Progra, A pilot project was launched which functioned for the next 5 years. In collaboration with Dr. A. Jeje (from Chemical and Petroleum Engineering), we offered high-level versions of courses in Solid and Fluid Mechanics for cohorts of about 20 students with outstanding academic credentials The initiative was eventually abandoned for lack of funding.
- A 1994 proposal on a degree in ‘Humanistic Engineering’, based on the concept of Engineering as a liberal discipline, led to presentations at U of C and the University of Victoria, and also to a publication in a national journal. It was never implemented in practice, but it begat a short-lived course in Reading of Original Scientific Texts and, eventually, the courses on the Latin of Science, still being taught after more than 20 years.

Graduate and post-graduate supervision

- Supervised 25 graduate students who completed their MSc or PhD theses.
- Hosted 12 foreign graduate students who spent various periods of time under my supervision as part of their graduate programs.
- Supervised 9 Research Associates and Post-Doctoral Fellows.

**Books and**

**Monographs**

NOTE: Each entry is followed by a short description of the content and impact of the work

- Material Geometry: Groupoids in Continuum Mechanics, World Scientific, 2021. Co-authored with Manuel de León and Victor Jimenez.

This research monograph is designed to fill a gap in the applied mathematics literature. The theory of groupoids is less than a century old. In recent years, it has been found to unify the structure of many physical theories with unparalleled power and elegance. In the field of Solid Mechanics, in joint work over the last 20 years with Manuel de León (Madrid), we have laid the foundations of the general theory of continuously distributed defects in materials in terms of groupoids. This book addresses the need to provide a presentation of the theory and its applications amenable to applied researchers.

- GeometricContinuum Mechanics, Springer Nature, Birkhäuser. 2020. Co-edited with Reuven Segev.

From the publisher: “Explores the mathematical foundations of continuum mechanics with a particular focus on geometric methods. Introduces applications of global analysis, algebraic topology, algebroids, groupoids, and geometric measure theory to continuum mechanics. Includes chapters written by authors who are experts in their respective areas, providing important insights from recent research.”

- The Latin of Science, Bolchazy-Carducci Publishers, Bolchazy-Carducci, 2019. Co-authored with Ruth Spivak.

Two courses on The Latin of Science have been established since 1995 at the University of Calgary. These courses can be considered unique in nature, since they are addressed to non-Classics majors while leading to a thorough ability to read scientific texts, written during a period of more than 20 centuries, in their original Latin version. In this book, now under production, we provide profusely annotated texts covering diverse scientific areas (such as Architecture, Astronomy, Medicine, Economics, Optics, and Philosophy of Science). An unusual feature of the book is that it provides the reader with facsimiles of manuscripts or first editions, intended to enhance the feeling of authenticity, much as when playing music in original period instruments. The book contains a complete grammar of the Latin language written in the spirit of science students, who look for patterns of similarity rather than minor differences, as is common in books written for Classics majors, who are driven to read classical Latin poetry or oratory.

- Partial Differential Equations, Springer, 2017.

Having taught for several years a graduate course (ENME 633) in PDEs and having developed a full set of notes and exercises relevant to Engineering applications, I decided to organize the material and propose it as a book for the Springer series Mathematical Techniques for Engineers. Although many other books exist, it appears that this book has been able to find a good balance between theory and applications, staying away from excesses in either direction. The target audience comprises primarily graduate students in engineering, but the book may also be beneficial for lecturers, and research experts both in academia in industry. The total number of chapter downloads from the Springer platform has been more than 13,600 since its recent publication.

- Differential Geometry, Springer, 2014.

Subtitled “Basic Notions and Physical Examples”, this book offers a concise introduction to the foundational ideas of modern Differential Geometry, with a view to its applications to Physics and Solid Mechanics. The book is the outgrowth of a mini-course delivered at the International Centre for Mathematical Sciences (ICMS) for a workshop on Differential Geometry and Continuum Mechanics held in Edinburgh in June 2013. The MAA Reviews stated that “this book is a gold mine of aesthetically pleasing mathematical ideas, the presentation of which is highly inspirational.” To date, the book or parts thereof has been downloaded from the Springer platform more than 13,500 times, apart from ordinary sales.

- The Elements of Continuum Biomechanics, Wiley, 2012.

This book is intended to serve as a high-level introduction for researchers applying the techniques of Continuum Mechanics to modeling biological tissues. The book is sprinkled with `case studies’, each of which presents a non-trivial application of the theory, including such non-standard topics as the use of mixture theory involving chemical reactions. Although not originally intended to display original research, the book has been cited 20 times in peer-reviewed journals.

- The Geometrical Language of Continuum Mechanics, Cambridge University Press, 2010.

This work presents a view of the discipline that summarizes the point of view propounded over a period of three decades with my collaborators. As such, it can be regarded as a labour of love, enhanced by the careful and elegant format provided by Cambridge University Press. The book opens with a motivational chapter to impress upon the reader that differential geometry is indeed the natural language of continuum mechanics. The abstract notions of differential geometry are illuminated by practical and intuitively meaningful engineering applications. An indication of the influence of this book in the Applied Mechanics community is that it has been cited over 100 times in articles published in peer-reviewed journals.

- Material Inhomogeneities and their evolution, Springer, 2007. Co-authored with M. Elzanowski.

This specialized monograph presents an original unified treatment of inhomogeneity theory using the tools of modern differential geometry.

Inhomogeneity theory is of importance for the description of a variety of material phenomena, including continuous distributions of dislocations, fracture mechanics, plasticity, biological remodelling and growth and, more generally, all processes that entail changes in the material body driven by forces known in literature as material or configurational. Chapters of this monograph have been downloaded from the Springer platform 5,100 times.

- Theoretical Models of Skeletal Muscle, Wiley, 1998. Co-authored with W. Herzog.

Written in collaboration with Walter Herzog, presently the Director of our prestigious Human Performance Laboratory, this book presents a thorough examination of the basic physiology and mechanics of skeletal muscle. This book is unique in the field and has had an unparalleled impact on the Biomechanics community, as demonstrated by over 220 citations. It is currently out of print.

- Epstein M (2018), Affine n-dimensional Statics, affine screws and Grassmann algebra,
*Mechanics Research Communications***94**, 74-79. Comments: The theory of screws is generalized to yield a formulation of Statics in higher-dimensional spaces in the absence of any distinguished metric structure. This level of generality necessitates the use of the tools of the exterior algebra of multi-vectors. The minimal structure retained serves to bring into relief the essential difference between screws and counter-screws as well as a weak version of the notion of rigid-body velocity field. An essential feature of the theory is the introduction of higher-order forces and displacements, whose relevance in the context of structured media can be determined in specific potential applications.

*Generalized Models and Non-Classical Approaches in Complex Materials 1*(Altenbach, H., Pouget, J., Rousseau, M., Collet, B., Michelitsch, Th. (Eds.)), 287-300. Comments: Within the theory of continuous distributions of defects in materials, this paper advocates a point of view based on the geometry of differential forms. Applications to smectic liquid crystals and to multi-walled nanotube composites serve to show how this dual mathematical approach fits perfectly with the intended physical reality. Moreover, the weak formulation of the theory in terms of de Rham currents delivers the description of discrete isolated dislocations as a generalization of the smooth theory.

*ZAMP*(Zeitschrift für angewandte Mathematik und Physik)**67**/6, 141-156. Comments: A modeling paradigm for continuous distributions of defects in multi-walled nanotube composites is proposed based on the theory of differential forms. A necessary and sufficient condition for a defect-free composite is derived and, concomitantly, a measure of defect density is proposed. Mathematically, this condition ensures the consistency of an over-determined system of partial differential equations. Physically, the condition expresses the fact that each multi-layered nanotube can find mutually coherent nanotubes in its neighborhood. Several examples of defect-free arrangements are presented and discussed.

*Journal of the Mechanics and Physics of Solids***84**, 72-84. Comments: In this paper, the various phenomena occurring in the evolution and growth of biological tissues are classified according to a rigorous mathematical criterion. More importantly, it is shown that, for certain cases (depending on the underlying material symmetry, such as isotropy and orthotropy), a sharp separation between these phenomena can be determined unequivocally. The importance of this fact is that experimentally measured properties can be attributed to each of these phenomena separately. Moreover, the generation of patterns (morphogenesis) can be described in terms of a symmetry braking that may be produced by purely mechanical (rather than chemical) causes.

*Mathematics and Mechanics of Solids*,**19**/4, 337-349. Comments: The passage from the smooth theory of distributed defects (shown to be describable in terms of differential forms) to the singular theory of isolated defects is achieved by the use of the theory of de Rham currents. A de Rham current can be regarded as a kind “Dirac delta” version of a differential form. Frank’s rules for dislocations and disclinations are shown to be straightforward consequences of the fact that the boundary of a boundary necessarily vanishes.

*Classical and Quantum Gravity***23**, 3545-3571. Comments: Teaming up with the English physicist Robin Tucker at the University of Lancaster, we considered the general relativistic version of a deformable anelastic body. One of the intriguing consequences of the analysis is that the spatial (uniformity) and temporal (evolution) of the classical formulation can no longer be split, but are observer-dependent.

- Epstein M and Sniatycki J (2006), Fractal Mechanics,
*Physica D***220**, 54-68. Comments: The geometrical theory of fractals, popularized among others by Benoit Mandelbrott, is well established. Nevertheless, if a material body can be considered to possess a fractal structure, how are we to express its elastic properties and mechanical response? In this article, we propose a formulation based on the geometrical theory of differential spaces, first introduced by Sikorski. A differential space is not necessarily a “continuum” and thus it lends itself to the possibility of describing more general material bodies.

Instead, we show how to solve it with any specified degree of accuracy. The proposed solution is exact, except for a step involving the finding of the root of an algebraic equation.

*Physics of Plasmas***7**, 906-910. Comments: This article has a curious history, since the area of Plasma Physics is neither my specialty nor that of my former PhD student Clifton Johnston (now an NSERC chair in Nova Scotia). The article, however, aroused significant interest in the Plasma community since it succeeded in obtaining an exact solution for a problem of propagation of nonlinear ion-acoustic solitary waves in cold collisionless plasma. Most importantly, we showed that the error committed by the use of standard perturbation techniques is very significant and can lead to severe underestimation of the amplitude of the wave.

*Mathematics & Mechanics of Solids***4**, 251-266. Comments: Second-grade materials, whose internal forces can be said to have a longer range than ordinary first-grade materials, require rather sophisticated mathematical tools, particularly in what pertains to the description of distributed material defects. This article presents the correct framework for the formulation of laws of evolution of these defects.

- Epstein M (1999), On the Wrinkling of Anisotropic Elastic Membranes, Journal of Elasticity
**55**, 99-109. Comments: The problem of wrinkling of elastic membranes has many applications, including the deployment of solar panels in space. The standard tension-field theory is here extended to anisotropic fabrics. The extension is far from trivial. It is achieved by showing that the wrinkling condition (namely, the appearance of compression) can be ingeniously understood in terms of the characteristic strips of a first-order non-linear PDE.

The limiting case of an infinite ladder of filaments is shown to approximate a preexistent continuous model.
