Abstract
The performance in resistance of structures and the lightening in weight lead the researchers and engineers to use various materials in the same structure designed to be in service. The study of bi-materials took a dominating place these last years. In this paper, various numerical analyses using the finite element method have been carried out to calculate the stress intensity factors at the tips of curved cracks in bi-material ring. For the case of homogeneous material with a curved crack, the obtained results in term of stress intensity factors gives a good agreement with the analytical expression for infinite plate with curved crack
