ABSTRACT:
A mandrel member has a series of projections formed therein in a predetermined pattern to represent a force-time history to be used in testing a member. A cutter member is provided for shearing off these projections. A driving force is provided so as to cause relative movement between the cutter member and the mandrel to effect the shearing of the projections. Vibratory energy in accordance with the characteristic force-time pattern of the projection configuration is generated with the shearing action and is transferred to the member to be tested.
