摘要：

A model for draping of woven fabric is described which is intermediate to the two main approaches currently used, kinematic modelling and comprehensive finite element modelling. The approach used is a simple unit-cell finite element model, with the fabric modelled by a network of simple truss elements, connected across the 'diagonals' by soft elements to mimic the shear stiffness of the material. Bias extension tests on dry fabric are used both to calibrate and validate the model. The model is then used to simulate draping of an ellipsoid. The capability of the model is illustrated by construction of a simple process optimisation map for this geometry. (C) 2004 Elsevier Ltd. All rights reserved.
