Laminated fiber-reinforced composite materials are vulnerable to damages arising due to impact events like accidental tool drops, bird strikes, etc. which result in significant reduction in structural integrity of these materials. Therefore, one of the popular adhesively bonded repair techniques i.e., patch repair is employed in this work. The present work focuses on the development of a three-dimensional energy based gradual degradation model for patch repaired laminate including the effects of shear non-linearity under tensile load. The model utilizes modified Hashin failure criteria for plain woven laminate and maximum shear stress criteria for the adhesive. The proposed numerical model is used to predict failure strengths for four different patch repaired configurations i.e., parent laminates of [0]4 and [45]4 each repaired with double sided patches of [0]2, [45]2, [0-45], [45-0]. Digital image correlation is employed with experiments to characterize mechanical and strength properties of the material and capture strain fields on the surface of the specimens. It is evident from the numerical results that the parent laminate of [0]4 repaired with [0]2 and [45]2 patches exhibit significant strength recovery under tensile load.
