The Pull‐Out experiment is used for determination of the bond strength between fiber and matrix an fiber reinforced composites. An interface crack growth between both constituents and a contact friction behaviour on the cracked area can be observed in the experiment. In our contribution this mechanical behaviour of the interface is simulated in the framework of Interface Damage Mechanics. The displacement discontinuities during the progressive decohesion are related to constitutive equations extended by a damage model. The contact/friction behaviour after complete separation is described by a friction model analogous to the classical theory of plasticity.
