The present study evaluates the Stress Intensity Factor (SIF) during the propagation of a crack interacting with a nearby circular dislocation. The problem is formulated using a numerical approach such as FEM along with the software (ABAQUS). The stress field and the SIF are determined for different crack's length. A brittle material such as a glass having an equivalent elasticity modulus and a Poisson rain this research work. Besides, the proposed model is a rectangular specimen with an edge crack subjected to tensile stresses according to the mode 1 opening. Obtained results are compared and agreed with those determined by other researchers.
