摘要：
In order to investigate the effect of an abnormally large grain on plastic responses of polycrystal, elasto-viscoplastic crystal plasticity finite element simulations were performed using synthetic three-dimensional microstructures with and without an abnormally large grain. The results indicated that the abnormally large grain could be an important feature in causing instability of mesoscopic plasticity by drawing hot spots of plastic shear. In particular, the maximum slip system shear hot spots are pronounced in the presence of the abnormally large grain oriented in single slip. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd.
