Thermal Stresses in a Thick Plate Containing an Oblate Spheroidal Inhomogeneity with the Circle Regions of both Plate Surfaces being Heated and Cooled

In this paper, we investigate the steady state thermal stresses in an elastic thick plate containing an oblate spheroidal inhomogeneity, 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 displac...

Summary:In this paper, we investigate the steady state thermal stresses in an elastic thick plate containing an oblate spheroidal inhomogeneity, 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 potential and Papkovich-Neuber displacement potentials. Numerical results are presented for different heat areas, inclusion shapes and sizes, and the stress distributions in the vicinity of the inhomogeneity are illustrated graphically.
