A two-dimensional generalized initially stressed magneto-thermoelastic problem for a half-space with voids

摘要

The present work is aimed at the analysis of the response of a homogeneous, isotropic, generalized thermoelastic half-space with voids permeated into a uniform magnetic field parallel to the bounding plane due to mechanical load acting on the initially stressed surface. The problem is studied in the context of generalized thermoelasticity with one relaxation time. Normal mode analysis is used to obtain the expressions for displacements, stresses, temperature distribution and change in Volume fraction field for thermally insulated as well as isothermal boundaries. Comparisons are made with the results predicted in the presence and absence of voids and initial stress.
