Conference paper


The J-integral for bi-material bodies in the presence of thermal stresses is derived. Using the equation obtained and the finite element technique, a procedure for extracting the crack tip stress intensity factor is developed. As a numerical example, a bi-material body with an edge crack under constant temperature gradient is solved.
