Thermal Stresses in a Thick Plate Containing an Oblate Spheroidal Inclusion with the Circle Regions of Both Plate Surfaces Being Heated and Cooled

Abstract

In the present paper, we investigate the steady state thermal stresses in an elastic thick plate containing an oblate spheroidal inclusion, when the circle regions of radius d of the upper surface is heated and the one of lower surface is cooled. The solution is deduced with using thermoelastic displacement potentials and Papcovich-Neuber displacement potentials. Numerical results are presented for different heat areas, inclusion shapes and sizes, and the stress distributions in the vicinity of the inclusion are illustrated graphically.
