Microstructure-Based Multiaxial Fatigue Analysis

The research objective is to examine the fatigue strength due to various microstructural features and crystal plasticity theories, and to implement a multiaxial fatigue failure prediction model. The material microstructure was generated by using a Voronoi diagram in the commercial finite element software ABAQUS, then uniaxial tension and shear simulation will be performed through the user-defined element of crystal plasticity. The macro level fatigue-life curves will be obtained and parametric studies will be performed to investigate the microstructure texture effect on the material fatigue-life curves. The fatigue failure prediction model can help operators predict possible failures of aircraft components.
