Dynamic cloth simulation by isogeometric analysis

摘要

A NURBS-based continuum approach of cloth simulation is presented. Cloth geometry is described by NURBS, and the dynamic response is modeled by displacement-only NURBS shell. The shell formulation, including a constitutive description for cloth-like materials and an algorithmic treatment of multi-patch models, is discussed in detail. A fully NURBS based contact/impact update algorithm is presented. Numerical examples are included to demonstrate the performance and the application of the method.
