In this work, the debonding process in filled plastics during constant strain rate tensile loading is analyzed both theoretically and experimentally. A model which combines concepts of damage mechanics and the time dependence of interfacial strength is proposed and compared with experimental results on glass bead filled polystyrene. The stress‐strain behavior and the debonding can be modeled using a Bartenev type relation for the destruction of the interfacial bond and by considering the gradual transformation on the initially well bonded composite into foam. A good agreement between calculated and experimental data was achieved.
