A Multi Material Shell Model for the Mechanical Analysis of Triaxial Braided Composites

An efficient numerical methodology based on a multi material shell (MMS) approximation is proposed in this paper for the analysis of the mechanical behavior of triaxial braided composites subjected to tensile loads. The model is based on a geometrical description of the textile architecture of the material at the Gauss point level of a standard shell including the corresponding yarn geometrical parameters. The mechanical properties at the yarn...
