摘要：

A new finite element method with the interface element was developed for examining the microstructural fracture behavior, where the anisotropy of grain was modeled by the ordinary finite element while both the opening and shear deformations was demonstrated by the interface element. From the serial computations using two-dimensional virtual polycrystalline models obtained through Voronoi tessellations, it was found that the interaction between the interaction between opening and shear deformations would be a dominant factor of the fracture processes. Also, it can be concluded that this method would be a useful tool for examining microstructural fracture behavior. (C) 2011 Published by Elsevier Ltd.
