Abstract : A study of the literature was made concerning the propagation of finite waves in nonlinear materials. This report includes a brief review of some of the significant contributions that resulted from this study. Results of both experiment and analysis were reviewed and the general state-of-the-art was determined. The majority of the effort was found to be centered on (1) general theories of nonlinear wave propagation, (2) experiments on finite amplitude waves, (3) determination of constitutive equations to describe nonlinear behavior, and (4) development of numerical methods of solution to describe wave propagation in nonlinear materials. Simultaneously, a computer program was developed using the method of finite differences for the solution of an initial boundary value problem. Some calculations were made for the propagation of waves in a nonlinear elastic material. This was intended to be compared with experimental results obtained at the Ballistic Research Laboratories.
