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 CLAY MATTE POMADE a full-space case.Different constitutive relations for the elastic medium, shell material and filling fluid can be considered, as well as different excitation sources (including S/P wave or plane/spherical incident wave at different locations).With mapmaking visualisation, the wave propagation phenomena can be described and better understood.
The methodology is going to be applied to analysis of the Signs/Plaques tunnels or other shell like structures under the effect of nearby underground explosion.
