The draping of fabrics over arbitrary surfaces: An augmented-Lagrangian method

A new numerical method, based on the augmented Lagrangian, for the draping of fabrics over arbitrary surfaces is reported. To the usual mesh-size cons traints are added two new constraints: the fabric location relative to the mould surface and the orientation of the fabric meshes. The draped configur ation is controlled by minimising the total deformation of the fabric. Nume rical draped configurations obtained by using the method are given.
