A numerical method for the analysis of one‐dimensional propagation of elastic–plastic stress waves in cylindrical bars is proposed. The method is based on the division of the bar into elements of finite length and the solution of the equations of motion for these elements. Numerical results are presented for semi‐infinite bars and a finite bar fixed at one end.
