Abstract:
In this work, an approach for a 3D material characterization based on experiments is presented. Experimentally determined material properties are used to define a 3D compliance matrix for a more accurate simulation of the material's behavior. This includes out-of-plane properties, e.g. transverse contraction in thickness direction. To gain complete stress-strain curves in material testing, Digital Image Correlation (DIC) is used for strain measurement. Through the usage of a biplane DIC-setup, out-of-plane measurements including strains in thickness direction are possible. Unidirectional endless fiber composites and short fiber plastic were tested in tension and compression to determine in-plane and out-of-plane material properties, each for two material orientations. «
