A technique, based on both the finite element and receptance methods, is developed by which the characteristics of interface joint inserts are introduced in the computer aided design of machine structures in general and specifically the case of drop hammers. The hammer frame, under investigation, is that of a one-third scale replica of an industrial drop hammer where the characteristics of the anvil/column interface joint are studied. The effect of both the experimental and theoretical properties of damping materials on the dynamic response of the hammer frame is also investigated.
