Abstract: The problem of one dimensional plane wave propagation is considered in isotropic, nonlinear, hysteretic materials. Solutions for surface loads of step pressure and/or shear, in cases of loading or unloading are studied, and the presence of shocks and regions of continuous stress change are discussed. The mathematical models used are a generalization of conventional elastic models. The moduli K are assumed to be functions of the stress invariant J₁, and the moduli G are functions of both J₁ and the stress deviators. Different expressions for K and G are used during loading and unloading, leading to energy loss through hysteresis.
