Use of combined CZM and XFEM techniques for the patch shape performance analysis on the behavior of a 2024-T3 Aluminum structure reinforced with a composite patch

Fracture and Structural Integrity, 2022
The presence of a geometric discontinuity such as a crack or a notch can cause the failure of a structure during its use. Under various mechanical or thermal stresses, a high concentration of stresses can take place at the level of these discontinuities,
