3D Analysis of Crack Behavior Using XFEM

Abstract:

It is important to evaluate the 3D crack behavior in the structures. In this study, a Crack-growth test and two simulations namely, Real-model simulation and Ideal-model simulation were performed using eXtended Finite Element Method (XFEM) to evaluate crack behavior three-dimensionally. In the Crack-growth test, crack behavior was observed for a notched metal specimen. In the Real-model simulation, the FE model was constructed using a 3D reconstruction model of the specimen, and crack growth was simulated. In the Ideal-model simulation, the simulation was performed using the FE model that involved ideal notch. The obtained crack growth simulation results were compared with tension test result. Crack growth in the specimen was evaluated three-dimensionally. It was shown that modeling the real shape of a structure with a crack may be essential for accurately evaluating 3D crack growth.
