Anisotropic Validation of Hexahedral Meshes for Composite Materials in Biomechanics

Abstract

We use a concrete simulation scenario to study the effect of hexahedral mesh size and mesh quality on the accuracy of the solution of a finite element analysis (FEA). Our test cases stem from biomedical research. We investigate a composite two-material model of a piece of bone from the human mandible on which we simulate a bite. In particular, we are interested whether material properties (soft vs. hard and isotropic vs. anisotropic) have a significant impact on the accuracy which can be achieved for the different kind of meshes
