Progressive interface failure in two-layer beams with partial shear connection is simulated. The mathe-matical model, based on classical beam theories and linear non-proportional interface laws, proposed previously by the authors, is considered. The related fundamental analytical solution is rewritten in vec-tor form to facilitate the determination of the high number of arbitrary constants on which the general solution for a generic conﬁguration of the composite beam, characterized by different regimes coexisting along the interface, depends. This is employed in the simulation of a process of progressive interface debonding as a sequence of equilibrated consecutive conﬁgurations assumed by the composite beam. Numerical analyses are ﬁnally performed to validate the solution procedure proposed.
