Calculation of stress intensity factors for bimaterial notches—thermal stresses

Publisher Summary In this chapter, linear elastic, isotropic, and homogeneous materials in the form of a bonded V-notch are studied. According to the linear theory of elasticity, the stresses in the neighborhood of the notch tip are generally singular. These stresses are characterized by eigenvalues, eigenfunctions, and stress intensity factors. Because of the highly singular behavior of one of the integrals, it is carried out by a hybrid analytical/numerical scheme. The finite element method is employed to obtain displacements caused by the temperature change in the body. A conservative integral is employed to determine the stress intensity factors for bimaterial notched bodies subjected to thermal stresses.
