The aim of this study is to estimate numerically the beneficial effect of adding patches for repairing cracks using the finite element method. The Stress Intensity Factors (SIFs) are obtained using patches. It is observed that with patch on the cracks there is a reduction of stress intensity factors. The effects of the adhesive, patch and plate properties on the rate of reduction of the stress intensity factors is highlighted. In this work, FRANC 2D/L has been used as an analysis tool to compare the SIF values for the plate with or without patches.Keywords
