Book excerpt: Across the centuries, the development and growth of mathematical concepts have been strongly stimulated by the needs of mechanics. Vector algebra was developed to describe the equilibrium of force systems and originated from Stevin's experiments (1548-1620). Vector analysis was then introduced to study velocity fields and force fields. Classical dynamics required the differential calculus developed by Newton (1687). Nevertheless, the concept of particle acceleration was the starting point for introducing a structured spacetime. Instantaneous velocity involved the set of particle positions in space. Vector algebra theory was not sufficient to compare the different velocities of a particle in the course of time. There was a need to (parallel) transport these velocities at a single point before any vector algebraic operation. The appropriate mathematical structure for this transport was the connection. I The Euclidean connection derived from the metric tensor of the referential body was the only connection used in mechanics for over two centuries. Then, major steps in the evolution of spacetime concepts were made by Einstein in 1905 (special relativity) and 1915 (general relativity) by using Riemannian connection. Slightly later, nonrelativistic spacetime which includes the main features of general relativity I It took about one and a half centuries for connection theory to be accepted as an independent theory in mathematics. Major steps for the connection concept are attributed to a series of findings: Riemann 1854, Christoffel 1869, Ricci 1888, Levi-Civita 1917, WeyJ 1918, Cartan 1923, Eshermann 1950.

Download or read book Thermomécanique des Milieux Continus written by Gatignol Renée and published by Éditions Cépaduès. This book was released on 2023-02-10 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage de « Thermomécanique des Milieux Continus » correspond à une introduction aux théories modernes de la mécanique des milieux continus. Les équations d’évolution des grandeurs décrivant le milieu ont pour origine : les lois physiques de bilan, éventuellement des lois supplémentaires liées à la microstructure du milieu, les lois d’état, et les lois de comportement complémentaires provenant de l’étude des mécanismes dissipatifs. Avec l’apparition de nouveaux matériaux ou de milieux possédant des comportements plus complexes que ceux de l’élasticité classique, de la plasticité ou du fluide visqueux, et par la nécessité de décrire des systèmes couplant de plus en plus les effets thermiques, mécaniques, électriques, magnétiques… la discipline Mécanique a beaucoup évolué au cours des dernières décennies, tant au niveau des concepts fondamentaux que de son unité. L’approche adoptée ici est phénoménologique. Elle s’appuie, pour les lois d’état sur l’axiome de l’état thermostatique associé, et pour les lois de comportement complémentaires sur l’étude de la dissipation dont la présence est inhérente à chaque milieu considéré. Concernant la dissipation, la théorie de la Thermodynamique des Phénomènes Irréversibles permet de construire des lois de comportement. Toute théorie cherchant à décrire des phénomènes physiques nécessite d’obtenir des validations expérimentales. L’observation et l’expérience sont primordiales pour aborder les problèmes de modélisation théorique relevant, soit d’outils mathématiques et analytiques, soit de simulations numériques (méthodes des volumes finis, formulations variationnelles…), celles-ci à l’heure actuelle, étant de plus en plus sophistiquées. Le plan de l’ouvrage est classique. 1. - Cinématique des milieux continus : Notion de milieu continu ; Description cinématique du milieu ; Grandeurs transportées par le mouvement ; Dérivées convectives. 2. - Déformation des milieux continus : Tenseur des dilatations de Green ; Déformations en théorie des petites perturbations ; Tenseurs définis à partir d’un placement réactualisé ; Tenseur des taux des déformations. 3. - Lois de bilan : Loi de bilan en description eulérienne ou lagrangienne : formes globale et locale, relation aux discontinuités ; Exemples de bilan de masse, quantité de mouvement, énergie pour un milieu continu classique ou polaire ; Introduction aux méthodes numériques des volumes finis. 4. - Principe des vitesses virtuelles : Concept de vitesses virtuelles ; Énoncé du principe ; Exemple du milieu continu classique, exemple des milieux diélectriques ; Théorie du second gradient ; Formulation spatialement faible d’une loi de bilan. 5. - Thermomécanique des milieux continus : Inégalités de l’entropie et de Clausius-Duhem ; Nécessité de lois de comportement ; Axiome de l’état local associé ; Affinités et flux généralisés ; Lois de comportement. 6. - Généralités sur les lois de comportement : Loi causale ; Loi locale, non locale, de type taux ; Changement de référentiels ; Grandeurs objectives ; Lois objectives ; Exemples des fluides proprement dits, et des milieux élastiques, hyperélastiques ou hypoélastiques. 7. - Exemples de milieux complexes : Six milieux sont présentés sous la forme de problèmes avec corrigés : mélanges de gaz, liquide à bulles, milieux granulaires, solutions de polymères, milieux poreux, et fluides doués de capillarité interne.

Book excerpt: Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters. Contents 1. Origins and Topicality of a Concept. 2. An Introductory Example of the Yield Design Approach. 3. The Continuum Mechanics Framework. 4. Primal Approach of the Theory of Yield Design. 5. Dual Approach of the Theory of Yield Design. 6. Kinematic Exterior Approach. 7. Ultimate Limit State Design from the Theory of Yield Design. 8. Optimality and Probability Approaches of Yield Design. 9. Yield Design of Structures. 10. Yield Design of Plates: the Model. 11. Yield Design of Plates Subjected to Pure Bending.

Book Synopsis Atom movements - Diffusion and mass transport in solids by : Jean-Marc Philibert
Download or read book Atom movements - Diffusion and mass transport in solids written by Jean-Marc Philibert and published by EDP Sciences. This book was released on 2006-05-01T00:00:00+02:00 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book is the result of diverse courses on diffusion. It is intended to give as complete an overview as possible of diffusion in solid media, while relating the process of diffusion to both their physical bases and their applications. A series of a real situations is covered in this account, from self-diffusion of radiotracers to the more complex cases of mass flow under chemical or thermal gradients or under electric fields, or diffusion in structures of lower dimensionality (surfaces and interfaces). In all these analyses, no category of materials was favored; metals, ionic crystals, oxydes, and semiconductors all had their turn. Only polymers were not specifically touched. One chapter is specifically devoted to techniques for studying diffusion, including methods of numerical simulation, and a last and long chapter gives a number of metallurgical phenomena in which diffusion plays a fundamental role.
