| Summary: | The aim of this project will be on the elastic-plastic stress study on crack-inclusion interaction in aerospace engineering materials (structures).
To analysis failure and various prevention of aerospace engineering materials and structures, the advanced finite element method (XFEM) has been widely used to simulate random cracks. In this project, a model is created to simulate the propagation of a crack in aerospace engineering materials. To analyze the material properties selected for this report, the crack propagation path, the propagation of the crack in the inclusion region will be simulated and analyzed.
This report introduces three simulation and analysis categories, including:
A single crack on a single metal with different interfaces with 10000 increments and 15 cycle load time.
Single crack with a 45-degree angle interaction case.
Multi-crack interaction case.
From the data obtained through simulation and analysis, various parameters which affect the fatigue life of the materials and structures will be analyzed.
