Abstract

The objective of this work concerns a numerical analysis by the three-dimensional finite element method, of the repair by simple composite patch of corroded and cracked Al 2024- T3 plates with a crack inclined to the horizontal at an angle teta=30. The effect of the adhesive shear modulus on the damaged area and on the DR damaged area ratio was considered. Then the effect of this parameter on the values of the DR and the J integral. The results obtained show the rectangular shape is the best because it makes it possible to obtain the lowest values of the J integral. In addition, it is best to use the elliptical shape after analyzing the results for the damaged area (DR) ratio.
