We introduce and study a variational model describing a reinforcing sheet, which is glued to an elastic-breakable matrix: the glue and the matrix react elastically to deformations up to a finite threshold. The analysis is performed in linear and nonlinear elasticity. The adhesion energy density is allowed to be neither convex nor differentiable. We provide a description of the conditions characterizing debonding and global collapse of the structure. A detailed analysis is performed in the case of a ring-shaped geometry.
