Polycrystal plasticity modeling of bulk forming with finite elements over orientation space
We focus on a class of polycrystal schemes developed by applying the finite element method to represent and compute the crystal orientation distribution function over an explicit discretization of orientation space. In particular, we extend the methodology to the modeling of three-dimensional polycrystals. The incremental Lagrangian scheme is applied to simulate the texturing of FCC crystals under monotonic deformations. Next, the finite element polycrystal scheme is employed to capture the development of spatial texture gradients in a bulk forming process.
