Crystal Plasticity Finite Element Simulation

Here I show some results obtained from continuum-based variational formulations used for describing the elastic–plastic deformation of anisotropic heterogeneous crystalline media. These approaches, commonly referred to as crystal plasticity finite-element models or crystal plasticity spectral models (depending on the solver method ), are important both for basic microstructure-based mechanical predictions as well as for engineering design and performance simulations involving anisotropic media.

Besides examples for the constitutive laws, kinematics, homogenization schemes and multiscale approaches behind these methods, I also present some examples, including, in particular, comparisons of the predictions with experiments. The applications stem from such diverse fields as orientation stability, microbeam bending, single-crystal and bicrystal deformation, nanoindentation, recrystallizationmultiphase steel (TRIP) deformation, and damage prediction for the microscopic and mesoscopic scales and multiscale predictions of rolling textures, cup drawing, Lankfort (r) values and stamping simulations for the macroscopic scale.
