A semi-implicit particle-based method is widely used for fabric simulation because of its calculation speed and realistic wrinkle expression. However, it is mechanically less accurate than a finite element method because basic mechanical terms such as Poisson’s ratio are not included in the formulation. We propose a new force term to emulate the Poisson effect in a particle-based cloth simulation. The new model was verified via the simulation of a uni-axial tension test and compared with the results of finite element analysis.
