Summary:The ever increasing use of textile reinforced composite materials for struc- tural applications makes the development of automated and computation- ally efficient analysis tools a must. In this paper, a micromechanical method for predicting the thermo-mechanical behaviour of textile reinforced (two- dimensional woven and braided fabrics) composites is presented. The model considers the shape and type of the yarns, yarn interactions and crimp as well as the matrix distribution. This modelling scheme consists of a mul- tilevel automated geometric decomposition of a representative volume el- ement (unit cell) into smaller elements (block and micro cells) conta
