Micromechanical modeling of the rolling of a A1050P aluminum sheet
Source abstract
Abstract
A micromechanical ductile fracture model, extended to take account thermal heating due to mechanical dissipation within the material, is used to study a 3D-asymmetric rolling operation. The void coalescence mechanism by intervoid material ligament necking is also considered by using an extension of the Thomason’s criteria. This formulation is implemented into ABAQUS/Explicit finite element package and applied to simulate the effects of some rolling parameters on the evolution of the voids volume fraction and voids shape of a A1050P aluminum. The confrontation with available experimental results shows the capability of this constitutive law to predict the rolling force variation for different reductions. The results show, on one hand, that optimum parameters could be found in order to reduce the rolling force and, on the other hand, that rolling parameters exert an influence on the final microstructure of the rolled metal.
