TLDR
In this paper, finite element computations of an oxygen-free, high-conductivity copper multicrystal under monotonic tension are presented, where a series of polishing operations are used to reveal the real three-dimensional (3D) microstructure, so that the mesh is a full 3-D mesh.About:

Saturation of Fragmentation During Severe Plastic Deformation
Reinhard Pippan,Stephan Scheriau,Aidan A. Taylor,Martin Hafok,Anton Hohenwarter,Andrea Bachmaier +5 more
TL;DR: In this paper, the saturation microstructure of a single-phase material was studied and it was shown that the saturation grain size decreases with decreasing deformation temperature, although the dependency is stronger at medium homologous temperatures and less in the low temperature regime.

Crystallographic texture evolution in bulk deformation processing of FCC metals
TL;DR: A Taylor-type polycrystalline model, together with a new fully-implicit timeintegration scheme has been developed and implemented in a finite element program to simulate the evolution of crystallographic texture during bulk deformation processing of face centered cubic metals deforming by crystallographic slip as mentioned in this paper.

An extension of the self-consistent scheme to plastically-flowing polycrystals
M. Berveiller,André Zaoui +1 more
TL;DR: In this paper, a self-consistent scheme is proposed for an isotropic elasto-plastic approximation of the "constraint" tensor, which leads to an explicit interaction law, modified from that of E. k roner (1961), which takes elastosplastic accommodation into account via a simple scalar "accommodation function".
Journal ArticleDOI
Computational homogenization analysis in finite plasticity Simulation of texture development in polycrystalline materials
TL;DR: In this paper, the deformation of a micro-structure is coupled with the local deformation at a typical material point of the macro-continuum by three alternative constraints of the microscopic fluctuation field.
