摘要
采用Bermin的孔洞成核的局部应力准则以及Euler坐标系下大应变有限元方法,分析了平面应变条件下二相粒子与基体在三种不同的界面结合强度下的宏观材料的力学行为.
A finite element method is used to study the cavity nucleation and growth in an elastic-plastic medium. The critical cohesion strength, σ_c at IPM (interface between second phase particle and matrix) is employed as the criterion of cavity formation. Three different values of σ_c are taken to examine their influence on the overall mechanical behaviour and process of cavity formation.
