Summary

The phenomena of crack growth and interface debonding can be regarded as the formation of a new surface. Thus, it is quite natural to model these problems by introducing the mechanism of surface formation. In the present report a method in which the formation of new surface is represented by interface element based on the interface potential energy is proposed. The general idea of the interface element and its application to peeling test of film, dynamic crack propagation, ductile tearing of steel plate and three-point bending test of heterogeneous material are presented.
