| Abstract Scope |
We present a demonstration of coupling between a continuous Galerkin hydrodynamic (CGH) finite element method and an elasto-viscoplastic fast Fourier Transform-based (EVPFFT) that we have advanced to allow for non-periodic velocity boundary conditions, which are achieved via Dirichlet boundary conditions. This advancement allows for the input to the micromechanical EVPFFT method to no longer be constrained to mean value information. The EVPFFT and CGH methods are both 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. |
