Abstract

In order to predict necking and fracture phenomena, a crystal plasticity model is introduced in the finite element analysis of tensile tests. Grains having different orientations are subjected to numerical tensile tests. A damage model is also proposed to predict the sudden drop of load carrying capacity after necking and to reflect the void nucleation and growth on the severely deformed region. From the analyses of tensile test, the necking and fracture phenomena are well predicted.
