review text: A method for the effective numerical treatment of the title problem is proposed. The interaction between the laminae due to the binding material is described by means of a nonmonotone, possibly multivalued law. By using the methods of nonsmooth mechanics, the problem is written as a hemivariational inequality and is transformed into a substationarity problem for nonconvex nonsmooth energy functions. Using the appropriate finite element discretization, the latter problem is formulated in finite dimensions. A `domain decomposition' type numerical approximation is proposed, and a new algorithm is developed for the numerical treatment of the delamination problem.
