Open-source implementations and comparison of explicit and implicit crystal-plasticity finite element methods
Year: 2024
Type: article
Abstract: In this study, two state-of-the-art implementations of the rate-dependent Crystal Plasticity Finite Element Method (CPFEM) as user material subroutines in the finite element solvers Abaqus/Explicit and Abaqus/Standard (Implicit) are presented. Adaptive substepping in the explicit solver and line-search stabilized implementation in the implicit solver enable fast and stable calculations also for small strain-rate sensitivities. A comparative analysis of simulation results is made and computation times of the two implementations are compared and discussed, including the use of reduced-integration elements and mass scaling for the explicit solver. It is identified under which conditions the explicit or the implicit solver is preferred.
