Abstract

We study the one-dimensional process of propagation of waves in a composite bar whose components have different cross sections and are made of dissimilar materials. The initial-boundary-value problem is posed for the key system of nonlinear equations for an arbitrary nonlinear elastic behavior of the materials. The developed numerical scheme is based on iterations and the finite-difference method. The shock compression of the split Hopkinson bar extensively used for the experimental investigation of the dynamic properties of materials is studied in detail.
