The presence of cracks has a major impact on the reliability of advanced materials, like fiber or particle reinforced composites or laminated composites. This paper presents different aspects of the interaction between crack and interface: stress field and fracture parameters for a crack approaching the interface and the crack deflection versus penetration for a crack with the tip on the interface. Different material combinations and mixed mode loads were considered by using a bi-axial bi-material specimen. The stress filed and fracture parameters were obtained numerically using the finite element method.
