Super-elasticity handling method in mass-spring model

A novel improved mass-spring model is analyzed and presented in this paper to settle down the super-elastic problem in the simulation of flexible gossamer. The virtual nonlinear springs, rather than linear Hooke springs, are adopted in the improved mass-spring model to effectively simulate the stress-strain response of flexible material and to show the physical properties realistically. The simulations reveal that the proposed improved mass-spring method can handle the super-elasticity phenomenon and definitely improved the simulation performance of flexible gossamer. The comparison with linear mass-spring model simulation also shows that better mechanical properties representation as well as the three-dimensional simulation performance can be obtained.
