The dynamics of delamination growth in layered plates as a result of delamination buckling is studied in the context of the model problem of a two layer circular plate with an initial penny-shaped delaminalion subject to a time dependent radial compressive load. The interaction of delamination buckling and normal impact is modeled through the application of a uniform transverse tension pulse, simulating the effect of a wave front passing through the layer interface, in conjunction with the radial loading. In addition three types of radial loading functions are considered independently and characcteristic features of the response are observed. Comparison is made with growth predictions made using a quasi-static analysis.
