The problem of increasing the longevity of damaged concrete structures is of major importance for economic reasons. The aim of this study is to analyze the mechanical behavior of a cracked concrete beam repaired with a composite patch. A finite element model was built to computerize the integral J around the crack localized along the beam thickness. The effects of different loading and repair parameters on the variation of the J-integral were analyzed. Based on these finite element calculations, we developed an analytical model for calculating the J-integral as a function of the various parameters. The results showed good agreement between the developed model and the finite element calculations.
