Title The solution of the unloading wave problem

Abstract The solution of Rakhmatulin's problem of an unloading wave for a linear strengthening scheme is extended to the case of large values of the maximum pressures. Two versions of the solution of this problem are also presented as they apply to the non-linear "stress-strain" diagram of elastoplastic materials: when this diagram is approximated by any number of linear sections and when, in the region of maximum stresses or an infinitely distant region, corresponding to the elastic limit, a rectilinear deformation section can be distinguished.
