A Problem Of Spherical Cavity In An In…nite Generalized Thermoelastic Medium With Double Porosity Subjected To Moving Heat Source



Authors : Kumar Rajneesh . Vohra Richa .

Abstract

This paper is concerned with the investigation of thermoelastic interactions in an isotropic unbounded medium with spherical cavity due to the presence of moving heat source in context of linear theory of thermoelasticity with one relaxation time [1]. Laplace transform technique has been used to obtain the expressions for radial stress, equilibrated stresses and temperature distribution. A numerical inversion technique has been applied to recover the resulting quantities in the physical domain. The components of stress and temperature distribution are depicted graphically to show the effect of heat source velocity and the relaxation time parameters. Some particular cases are also deduced from the present investigation.
