Meso-Fe models of tight 3D woven structures

The aim of this work is to produce a realistic description of fabric topology and internal geometry of two warp interlock 3D textile architectures: orthogonal interlock/through-thickness (O/T) and angle interlock/through- thickness (A/T). The solid models are intended for finite element simulations of fabric behaviour. The first step in modelling is approximate description of geometry provided by the WiseTex tool, which reproduces fabric topology and position of warp/weft/Z-yarn families, but does not account for the lateral interactions of the warp yarns in tight fabrics and variation of cross-section shape along the yarn midlines. The initial model is then processed to create solid models with non-intersecting yarn volumes and to tune parameters for correspondence with real micro geometry.
