The problem of transverse impact against an unbounded flexible plate is the topic of a number of papers. In all these research papers it is assumed that the high tensile impact-wave velocity does not exceed the longitudinal wave velocity. Consequently, under this assumption, after impact two regions occur the region of purely longitudinal motion and the region of transverse motion. This picture of the motion is characteristic of impact by a pointed body. The paper contains an investigation of impact of a blunt body against a flexible plate for which the high tensile impact wave velocity exceeds the speed of sound in the material.
