The solid bodies constituting the adhesively bonded joint, i.e. the adhesive and the adherends, are treated as material surfaces. The result can be regarded as a structural element model of the compound joint. The adhesive is modelled as a softening material due to local material damage. As a consequence, the propagation of a crack front in the adhesive layer can be followed, and the failure load of the structure becomes a computational result. A one-parameter viscous regularization of the softening adhesive material law is used in order to improve the numerical behavior. Several applications are presented
