Abstract

Abstract The subject of this article around two studies, including experimental and numerical, aiming to know the efficiency of the repair of a composite plate notched (V-shape) and cracked by composite patches of different (types and shapes) . The experimental study to find out which composite materials and shapes are resistant to fracture and notch, We used the finite element method (ABAQUS) for the numerical study to follow the variation of the damaged area ratio DR, the stress intensity factor SIF and the stress distribution as a function of the crack size for located the most effective shape and type patch in repairing cracks and notch. From the results found we can deduce that the best type of patch used is Boron / epoxy and the full shape is the most efficient and resists structural failure, this is confirmed by the experimental test.
