Abstract

A phenomenological approach which has found numerous applications for all kinds of decohesion and separation processes is based on Barenblatt’s idea of a cohesive zone. The basic concept and numerical realisation in the framework of finite elements are described. A number of proposed traction-separation laws for various applications including mixed mode and the physical significance of the cohesive parameters are discussed. Recent approaches to relate decohesion laws to damage mechanics are critically reviewed. Examples of applications to the simulation of crack extension in thin panels and shells are presented.
