This study investigates functionally graded materials (FGMs) as reinforcement for notched plates prone to crack propagation. Using a novel meshing technique and the Gurson-Tvergaard-Needleman damage model within ABAQUS-Explicit, we explore how various gradation parameters affect material under stress. The model, incorporating Von Mises stress theory Voce hardening law, simulates plastic flow progressive from void dynamics. Validated against experimental data, our findings reveal that local significantly influence structural performance of components. research provides crucial insights into FGMs' potential enhance integrity in engineering applications involving structures.
