Three-dimensional modeling to compute plastic zone in front of crack in compact tension sample of multiphase material

Two-dimensional modeling to compute plastic zone in front of a crack in a compact tension specimen of a multiphase material was published previously. This paper is the continuation of it, using the same concept, but in three dimensions. The heart of this study is to develop a simulation method to pr...

Three-dimensional modeling to compute plastic zone in front of crack in compact tension sample of multiphase material
description Two-dimensional modeling to compute plastic zone in front of a crack in a compact tension specimen of a multiphase material was published previously.
