A suited mesh for identification of macroscopic elastic parameters of a coarse microstructure of a 3D woven composite from digital image correlation

Abstract : This paper focuses on the identification of homogenized macroscopic elastic parameters on a 3D woven composite, based on Digital Image Correlation and the Finite Element Update Method. One major difficulty consists in handling a rather coarse microstructure. A fine mesh analysis of the kinematics captures both the details of the three point bending test, but also the microstructure induced modulation of the displacement field, which is out-of-reach of a homogenized representation. A compromise, based on an adjustment of the mesh size used for the correlation analysis and the weaving period is shown to be satisfactory.
