Split singularities and the competition between crack penetration and debond...
Zhen Zhang and Zhigang SuoFor a crack impinging upon a bimaterial interface at an angle, the singular stress field is a linear superposition of two modes, usually of unequal exponents, either a pair of...
View ArticleMax penetration error in ABAQUS
I am doing contact simulation of soft material. I want to change the default criterion for max penetration error, but can't seem to find how to do it. I tried contact controls relative and absolute...
View ArticleReg. Penetrations in a Contact Analysis Code
Hi, I have developed a FORTRAN code to simulate the molding process of glass to make lenses. Hence, it involves a contact analysis between the glass and molds. The contact is modeled using the...
View ArticleCrack penetration in cohesive zone models
Hi all, I am conducting some cohesive crack simulations within the framework of XFEM. The cohesive model is an initially rigid traction-separation law for mode I. In order to deal with negative...
