| Abstract Scope |
Crystal Plasticity models are increasingly used in engineering applications to obtain microstructure-sensitive mechanical response of polycrystalline materials. These models require a proper consideration of the single crystal deformation mechanisms, a representative description of the microstructure, and an appropriate scheme to connect the microstates with the macroscopic response. The latter can be based on homogenization, which relies on a statistical description of the microstructure, or on full-field solutions, which requires a spatial description of the microstructure. Full-field Fast Fourier Transform (FFT)-based methods are attractive due their relative higher efficiency and direct use of voxelized microstructural images. In this talk, we will report recent progress on FFT-based polycrystal plasticity, with emphasis in novel implementations for advanced constitutive regimes, including large-strain elasto-visco-plasticity, strain-gradient plasticity, field dislocation mechanics, and dynamic deformation regimes including inertia, along with integration with emerging 3-D characterization methods in Experimental Mechanics. |
