DEFORMATION DUE TO MECHANICAL AND THERMAL SOURCES IN GENERALIZED THERMOELASTIC HALF-SPACE WITH VOIDS

ABSTRACT

The dynamic response of a homogeneous, isotropic, generalized thermoelastic half-space with voids subjected to normal, tangential force and thermal source is investigated. The displacements, stresses, temperature distribution, and change in volume fraction field so obtained in the physical domain are computed numerically and illustrated graphically. The numerical results of these quantities for magnesium crystal-like material are illustrated to depict the response of various sources in the Lord–Shulman and Green–Lindsay theories for an insulated boundary and temperature gradient boundary.
