Abstract :
Within the scope of the model of a quasi-plane wave, the propagation of a strain pulse in a given direction in solids with an inhomogeneous stress field is considered. The effect of the non-homogeneity of the initial stress-strain state on the pulse propagation time and its shape change is studied.
