Abstract The problem of spherical shock wave propagation in an elastic-plastic medium is solved analytically and numerically by the method of characteristics on the basis of the strain theory, including the generalized equations of state of the medium. The spherical shock wave propagation in an elastic-plastic medium with a more complex equation of state for the medium forming is studied. The results show that an account for nonlinear–elastic shock diagrams leads to an increase in circular stress wave compared to an elastic medium. It was found that the stress concentration is higher on the spherical cavity than on the cylindrical one.
