| Abstract Scope |
We present a method of directly coupling a micromechanical method to a continuous Galerkin hydrodynamic (CGH) finite element method beyond simple mean value passing. The micromechanical part is an elasto-viscoplastic fast Fourier Transform-based (EVPFFT) method that we have advanced to allow for both non-periodic velocity boundary conditions, achieved via Dirichlet boundary conditions, as well as dynamic effects. The CGH method is a part of the open-source Fierro mechanics code, which incorporates the C++ Matrix and Array (MATAR) library for productivity, performance, and portability across computer architectures, leading to efficient simulation times for this advanced material modeling. We demonstrate the results of both simple and complex coupling methods using Taylor anvil simulations based on experiments. |
