AbstractรA model that describes the temporal evolution of an initial grain size distribution (GSD) has been used to analyze the eect of initial GSD on grain growth. Based upon the work of Hillert, and Hunderi and Ryum, this model uses a ยฎnite dierence technique to numerically solve the continuity eq

A numerical procedure is described for directly simulating the generation of a microcrack process zone around a crack during loading. The interactions between microcrack-microcrack and microcrack-main crack were realized and certain effects of interaction predicted by the theoretical model are corro
Previous experimental observations on some nanostructured metals have indicated a transition from homogeneous to non-homogeneous plastic deformation with a reduction in grain size [Jia D, Ramesh KT, Ma E. Acta Mater 2003;51:349]. We present a model that predicts the development of shear bands in suc
