The present paper deals with the disturbances due to periodic strip thermal sources, acting on the rigidly fixed, charge free (open circuit) or electrically shorted (closed circuit) surface of a homogeneous, transversely isotropic, thermally conducting generalized piezothermoelastic half-space. The Laplace and Fourier transform technique have been employed to solve the model consisting of partial differential equations and boundary conditions in the transformed domain. In order to obtain the displacements, temperature change, stresses, electric potential and electric displacement in the physical domain, the integral transforms have been inverted by using a numerical inversion technique. Finally, to illustrate the analytical results, the numerical computations of various field parameters have been carried out from the relevant expressions and relations for cadmium selenide (CdSe) material by developing a FORTRAN code. The computer simulated results are presented graphically in respect of different considered field functions with load frequency and epicentral distance for 6 mm cadmium selenide (CdSe) material half-space.
