Abstract

The chapter starts from description of geometrical models of 2D and 3D woven fabrics, with an aim of creation of meso-level (textile unit cell) finite element (FE) models, and proceeds to micromechanics of woven composites, based on the method of inclusions/Mori-Tanaka homogenisation and FE analysis of the stress–strain state of the unit cell. Special attention is paid to geometrical consistency of the FE models. CDM-type damage model is presented and an example of FE modelling of a woven composite is given.
