The paper presents a numerical investigation of mixed-mode crack induced failure of concrete beam strengthened with steel plate. Both the cracking of the concrete and concrete-steel interfacial debonding can be observed. There is a shear stress concentration at the pre-existing crack or debonding tips, which is the root cause of the debonding. The results indicate that debonding only initiates and propagates along the left interface to the steel plate because that the normal stress along the left interface is tensile which make considerable contribution to the debonding and the normal stress along the right interface is compressive.
