Thermal Stresses around two cracks in an infinite elastic layer between a ceramic-fiber-reinforced half-plane and a metallic half-plane

Abstract

Thermal stresses around two cracks in an infinite elastic layer between a ceramic-fiber-reinforced half-plane and a metallic half-plane are solved. The surfaces of the crack are assumed to be insulated. The boundary conditions are reduced to dual integral equations using the Fourier transform technique. To satisfy the boundary conditions outside the cracks, a difference in temperature at the crack surfaces and differences in displacements are expanded in a series of functions that vanish outside the crack. The unknown coefficients in each series are evaluated using Schmidt method. Stress intensity factors are then calculated numerically for several thicknesses of the layer.
