NUMERICAL STUDY OF MECHANICAL BEHAVIOR OF REPAIRED INCLINED CRACKED UNDER COMPLEX SHEAR-SHEAR LOAD: PERFORMANCE AND DURABILITY OF ALUMINUM 2024-T3 PLATE
In this study, a finite element model was developed to analyze the mechanical behavior of repairing aluminum 2024-T3 structures subjected to complex shear-shear loads using composite patch repair techniques. The study aimed to investigate the effect of different patch sequences on the mechanical behavior of the repaired structure, including the orientation of the fiber patch, to improve durability under complex shear-shear loading conditions. The study demonstrated that the FEM approach is a robust and precise method for optimizing patch repair and studying the effect of mechanical loads on patch repair effectiveness for aluminum 2024-T3 structures.
