The multi-scale finite element method (MsFEM) and a multi-scale model for fabric material are introduced. MsFEM methods can capture the effect of small scales on the large scales without resolving all the small scale features. The model is based on the assumption that, at the continuum level, fabric behaves as a finitely deformable membrane. Moreover, the fabric is assumed to be composed of two families of continuously distributed yarns constrained at all time to occupy a common evolving surface in three dimensional spaces. Draping and buckling of woven fabric are simulated with multi-scale finite element method. The simulated results are in good agreement with the experimental observations. The results show that precision of the draping and buckling simulation is improved evidently because of the multi-scale model. The investigation sets up the theory and technique basis for the fitting system in the dress CAD.
