Abstract


In this paper we will discuss the problem of distribution of thermal stresses and temperature in a generalized magneto–thermo-viscoelastic solid spherical cavity of radius R according to Green- Naghdi (G-N II) and (G-N III) theory. The surface of the cavity is assumed to be free traction and subjected to a constant thermal shock. The Laplace transform technique is used to solve the problem. The state space approach is adopted for the solution of one dimensional problem.  Solution of the problem in the physical domain are obtained by using a numerical method of MATLAP Programmer and the expression for the temperature, strain and stress are obtained. Numerical computations are carried out for a particular material for illustrating the results. Finally the results obtained are presented graphically to show the effect of time on the field. A comparison is made between G-N II and G-N III models.
