   Abstract:
   A rigid perfectly plastic model is developed to study the effects of a central crack on the plastic response of a beam subjected to a central transverse impact load. The governing differential equations are expressed in terms of non-dimensional parameters representing the crack size, beam to projectile mass ration, and energy input. The equations are solved numerically to obtain general solutions, and the effects of the parameters on the final permanent deformation are isolated and studied to identify the relative significance of each parameter. © 1985.
