The main objective of the present paper is numerical analysis of the micro crack propagation along a composite interface. Hence, the finite element technique was used to calculate the opening-mode and sliding-mode stress intensity factors. A two-dimensional linear elastic model was developed to investigate the initiation of a ring-shaped matrix crack from the end of single sized continuous-fibre reinforced metal matrix composite, subjected to tensile loading. The effect of the applied load, mechanical properties of the composite materials, and fibre volume fraction on crack growth was studied. Moreover, effects of the existence of defects (precipitate, and micro-void) are also discussed
