Abstract Scope |
The effects of secondary particles and voids on the plastic deformation of aluminum alloy are investigated using crystal plasticity finite element (CPFE) simulations and high energy X-ray diffraction microscopy (HEDM) techniques. HEDM and X-ray computed tomography (XCT) are used to fully construct 3D microstructure of polycrystalline Al2219, identifying grain orientations and the spatial distributions of particles and voids. The CPFE model is utilized to simulate uniaxial tension of the characterized polycrystalline microstructure, both with and without defects. The predicted local fields are compared with experimentally measured grain-average elastic strains and therefore determine grain-level stresses. In addition, observed crack locations are analyzed in relation to CPFE simulations with and without voids and particles. This work demonstrates effects of incorporating realistic distributions of secondary particles and voids in finite element predictions of local response, as well as in understanding failure and fracture behavior. |
