On the Propagation of Waves in a Physically Nonlinear Medium Weakened by a Cylindrical or Spherical Cavity,

Abstract

Differential equations of the propagation of cylindrical waves are obtained taking into account the change of volume and form in a nonlinear elastic medium. The fundamental equations for compressible and incompressible materials are found, taking into account small physical nonlinearity. The fundamental equations of the propagation of spherical waves in a nonlinear elastic medium are determined for small physical nonlinearity, which is characterized by the square of deformation intensity.
