Large Amplitude Waves in Bounded Media. II. The Initial Deformation of an Impulsively Loaded Slab,
Abstract
The paper continues the investigation of large amplitude waves in bounded media started by H. M. Cekirge and E. Varley (1973). It describes the early stages of the deformation produced in an elastic slab contained between two parallel, plane interfaces when the normal traction at one of them changes discontinuously. During the subsequent deformation energy is radiated across these interfaces to adjacent elastic materials. The disturbance in the slab could be caused by the arrival of a constant strength shock wave traveling through an adjacent material or when the slab, which forms part of a composite material, impacts some other elastic material. It is assumed that the dynamic response of the slab can be approximated by that of one of the model materials introduced in the first part of this study. It is shown that this is possible for a whole host of materials. These include polycrystalline solids, metals when subjected to high pressure, water, explosive products, gases and yarns as well as elastic-plastic, rigid-plastic and rigid-elastic materials.
