Modelling of Finite Deformations of Anisotropic MaterialsWe present some examples of the application of invariant theory to the formulation of constitutive equations for anisotropic materials, and in particular for fibre-reinforced materials. The approach is illustrated by the formulation of constitutive equations in finite elasticity, in heat conduction, and in plasticity.

Déformations Finies des Agrégats Métaux: Aspects Physiques et MétallurgiquesOn passe en revue les processus microscopiques mis en jeu dans les phénomènes de glissement cristallin et de diffusion. On compare la situation des agrégats polycristallins au r?le de la structure mosa?que des monocristaux. On se limite essentiellement aux métaux purs.

Chivalrous

Microlocal Aspects of Finite Deformations in the Light of Nonstandard Analysiss and by means of an approach analogous to the known method of internal constraints. It is shown that, under certain regularity conditions, different homogenized models describing microlocal effects of the composites under consideration can be derived directly from the nonstandard form of the governing relations.

A Unified Elastic-Viscoplastic Theory with Large Deformationsstress and plastic strain rate. Generalization of the theory to large deformations has been carried out using Lagrangian quantities and thermodynamic restrictions. Examples of simple tension and simple shear show that the large strain theory produces physically plausible results.

Sur Quelques Concepts Fondamentaux de la Mécanique lois de comportement au moyen de deux potentiels convexes—une généralisation de la thermodynamique des processus irréversibles. Une interprétation des variables internes comme schématisation de la modification des propriétés de la matière est suggérée.

Mediocre

The Effect of Partial Reversibility of Dislocation Motionternately (x–y tests). (3) Mechanical analysis predicts that a large fraction of the mobile dislocations do not move when the tensile direction is changed over 90°. Macroscopic x–y tests on aluminium and copper show that the strain hardening coefficient decreases after each change.
