Abstract

A law of normal and tangential adhesion-decohesion is added to the classical law of unilateral contact with threshold friction. That law is formulated within the framework of standard generalised materials. The model originality stems from the use of an irreversible adhesion gap g a (similar to a plastic strain) as damage internal variable and a rate independent decohesion law. The three laws of contact, friction and adhesion are derived from their respective (quasi-) potentials and then penalised before being implemented in a finite element code. Since the law is developed to study debonding and damage in fibrous composites, the standard pull-out test is used to demonstrate its validity.
