Abstract: “Disturbances caused by impulsive mechanical source in a homogeneous, isotropic half-space are studied within the context of generalized thermoelastic diffusion with one relaxation time. A two dimensional half space with a permeating substance in contact with the bounding plane is considered in axisymmetric distribution. The chemical potential is assumed to be a known function of time. Integral transform technique is used to find the analytic solution in the transform domain by using direct approach. Inversion of transforms is done employing a numerical scheme. Mathematical model is prepared for Copper material and numerical results for temperature, stress, displacement, chemical potential and concentration are obtained and illustrated graphically”
