title = "Macroscopic yield function predicted by crystal plasticity simulation on ultrafine-grained aluminum",
abstract = "In this study, using experiment results obtained by electron backscatter diffraction, information on crystal orientation is introduced into a computational model for crystal plasticity simulation considering the effects of grain boundaries and dislocation sources to express the effect of the microstructure of ultrafine-grained metals. Finite-element simulations are performed for a polycrystal of an aluminum plate under biaxial tension. The multiscale crystal plasticity simulations depict the yield surface of the ultrafine-grained aluminum produced by accumulative roll-bonding processes. The anisotropic material coefficients of a higher-ordered yield function for ultrafine-grained aluminum are derived using a genetic algorithm.",
