Abstract

Understanding the failure mechanisms of highly heterogeneous materials requires a detailed knowledge of the micro-structure and the underlying material properties. For bone, this level of information can be obtained from high-resolution computed tomography (CT). In finite element analysis (FEA), the amount of structural information combined with nonlinear material models, calls for highly efficient and parallel software tools. In order to provide such a solver, ParOSol, an existing high-performance linear solver, was extended to incorporate a simple damaged based material model. The FEA solution is found by iteratively applying the linear solver. The new solver was tested on several structures: A simple cuboid for numerical verification, a trabecular bone cube for optimizing the solver parameters and a radius segment (688 million degrees of freedom) for performance evaluation.
