The paper addresses the problem of transient elastodynamics analysis of a thick-walled. fluid-filled spherical shell embedded in an elastic medium with an analytical approach. This configuration is investigated at first step for a full-space case. Different constitutive relations for the elastic medium. https://www.spidertattooz.com/Essie-Gel-Couture-Inside-Scoop-0-5-oz-1088-p15287/
