| Abstract: | In this paper the author examined the strain in the interior of the earth by using the elastic dynamics.The interior of the earth is inhomogeneous and its density distribution is described by the Helmelt's law.The theoretical expressions for the radial and transverse components of strains in the interior of such earth's model are derived,and numerical computation for the radial compnents of strain in the earth crust are presented. |
