| Abstract Scope |
Multiaxial stress state causes complex deformation in sheet metal forming. Sheet metals produced by severely rolling show mechanical anisotropy depending on the strong rolling texture. While crystal plasticity simulations considering actual microstructure information has attracted attention with developing of microscopic observation of metals using the electron backscattered diffraction pattern (EBSD) method. However, a uniaxial tensile test generally determines mechanical properties used for the crystal plasticity simulation by neglecting the mechanical anisotropy. In this study, crystal plasticity simulation on severely rolled metals is carried out to investigate the effects of microstructures of metals on mechanical properties. Yield surfaces are predicted by crystal plasticity analyses based on the microstructure observed using EBSD method and stress-strain curves obtained by uniaxial and biaxial tensile tests. Extreme value distributions of mechanical properties estimate the effects of the microstructures. |
