title = "Formula for SIF of cracked steel plates strengthened with CFRP plate",
abstract = "Fatigue loading will lead to crack initiation and crack growth in steel structures where stress concentration exists. Fatigue life of aged steel members can be extended significantly with carbon fiber reinforced polymer (CFRP) repair. Stress intensity factor (SIF) is a key parameter to calculate the fatigue life and analyze the progress of crack development. There is a lack of knowledge of SIF for cracked steel plate with different degrees of damage strengthened with CFRP. This paper aims to fill this knowledge gap. The SIF formula is developed based on the classical SIF solution and James-Anderson method by considering two correction factors, representing the effect of load share effect in composite system and the effect of initial damage degree, respectively. It is demonstrated that the SIF formula proposed in the paper is applicable to SIF estimation of strengthened center cracked steel plate with different degrees of damage.",
