| Abstract Scope |
The Finite Element Method (FEM) is often used to simulate deformation, but high temperature processes can additionally involve grain boundary motion that is difficult within existing FEM simulations. The FEM simulations that do exist cannot generally be used for predictive purposes because they do not allow for anisotropic grain boundary properties, have unphysical anisotropy from the underlying numerical model, or allow only a restricted set of topological events that bias the grain boundary network evolution. Recent progress will be reported in developing a FEM simulation that (1) uses a volumetric mesh to eventually allow the inclusion of arbitrary material physics, (2) significantly expands the set of topological events to allow for general grain boundary network dynamics, and (3) proposes an energy dissipation criterion to identify the physically most plausible of these events. Moreover, the performance of three proposed equations of motion will be evaluated and compared to analytical results. |
