An advanced elastic-plastic self-consistent polycrystalline model, accounting for intragranular microstructure development and evolution, is coupled with a bifurcation-based localization criterion and applied to the numerical investigation of the imp

Micro–macro scale transition theories were developed to model the inelastic behaviour of polycrystals starting from the local behaviour of the grains. The anisotropy of the plastic behaviour of polycrystalline metals was essentially explained by ta

In this paper, a new micromechanical approach accounting for the discreteness of intragranular slip is used to derive the local misorientations in the case of plastically deformed polycrystalline nickel in uniaxial tension. This intragranular microst

A new micromechanical modelling is proposed to correlate some microstructural parameters and dissipation in ferritic steels under cyclic loading. We assumed the occurrence of two dissipative mechanisms associated with anelastic and inelastic deformat

Although homogenization methods based on the Eshelby inclusion problem well capture the effects of heterogeneous local behaviours, volume fractions and morphologies of constituents on the macroscopic behaviour, inclusion size is still not considered.

International audience; A grain-size dependent accommodation law for polycrystals is deduced from an inclusion/matrix problem (i.e., each grain is seen as embedded in a homogeneous equivalent medium) where plastic strain inside the inclusion is given

When the mean grain size of polycrystalline materials is larger than ∼100 nm, it is commonly accepted for metals, intermetallics or ceramics that the plastic flow stress scales linearly with the inverse square root of the mean grain size (the so-ca

Through a micromechanical and physical modelling, hardening occurring after a pre-straining step and a static aging step––matching the deep drawing and the paint baking processes––is simulated for an Al-killed low carbon bake hardening steel
