Automatic transformation of 3D micro-CT images into finite element models with anisotropic local properties

Abstract Finite element models derived from micro-CT images can be used for modelling of the actual material geometry and prediction of mechanical properties. The primary direction of anisotropy in a composite material is determined by the orientation of fibres, which can be calculated by means of the structure tensor. This paper presents results on direct conversion of a 3D micro-CT image into the finite element model with anisotropic local mechanical properties of the reinforcement.
