New bounds and estimates for porous media with rigid perfectly plastic matrix

Nicolas Bilger; François Auslender; Michel Bornert; Renaud Masson

Abstract We derive new rigorous bounds and self-consistent estimates for the effective yield surface of porous media with a rigid perfectly plastic matrix and a microstructure similar to Hashins composite spheres assemblage. These results arise from a homogenisation technique that combines a pattern-based modelling for linear composite materials and a variational formulation for nonlinear media. To cite this article: N. Bilger et al., C. R. Mecanique 330 (2002) 127–132.

Applying the virtual fields method to determine the through-thickness moduli of thick composites with a nonlinear shear response

Michel Grédiac; François Auslender; Fabrice Pierron

This paper presents a method allowing the simultaneous identification of parameters governing an orthotropic law with a nonlinear shear response. Such laws appear for instance through the thickness of thick laminated composites. The tested specimen is subjected to boundary conditions similar to those of a Iosipescu setup. The strain field in the central area is processed with the so-called virtual fields method, which is an application of the principle of virtual work with particular virtual fields. The method is simulated with data obtained from finite element calculations.

An “Affine” Micromechanical Approach for the Prediction of the Elastoplastic Behavior of Polycrystals at Finite Strain

François Auslender; Michel Bornert; A. Zaoui; T. Hoc; R. Masson

The so-called “affine” formulation, already proposed at small strain, has been proved to improve significantly on former treatments such as Hill’s incremental one. This paper reports on an extension of this treatment at finite strain. A linearization procedure, consistent with the one used for small strains, is proposed. This extension has to solve general problems related to the application of classical homogenization schemes to finite strain situations, as well as new ones which are specific to the affine formulation. Preliminary results concerning the tensile stress-strain response of FCC polycrystals are favorably compared with those derived from Hill’s approach.
