Abstract : One-dimensional wave propagation in a semi-infinite strain-hardening rod loaded at one end by a suddenly applied and thereafter monotonically decreasing compressive stress is considered. The general problem is discussed and expressions for stress, strain and velocity, together with the governing differential equations for a strain-hardening shock wave are given in their general forms. Closed-form solutions are obtained for stress-strain relations consisting of a power law for loading beyond an initial elastic range and a constant strain law for unloading in the entire range of strain.
