Abstract

In this study, we investigated the influence of microscopic structures of highly cold-rolled pure aluminum A1050 on macroscopic mechanical properties based on the crystal plasticity finite element (FE) analysis. Uniaxial tensile tests and biaxial tensile tests were performed, and the contours of plastic work were plotted. The comparison of experimental results and results obtained by the crystal plasticity FE simulation with a small number of grains indicates that the yield strength for the rolling direction was higher than that for the transverse direction of the rolled sheet; however, the experimental and numerical yield surfaces did not agree. Extreme value analysis was used to estimate the variation of mechanical properties in simulated results due to the combination of crystal orientation in the computational models employed.
