On verification and validation of spring fabric model

An enhanced spring-mass model has been developed to mimic the complex behavior of parachute canopy in the air flow. Given the Young's modulus and Poisson's ratio, the model has the ability to duplicate the realistic strain and stress of the elastic membrane by including the angular deformation energy in the triangulated mesh. The numerical results verify the effectiveness of the proposed model and demonstrate its convergent property. In addition, GPU-based parallel computing techniques are applied to accelerate the computational speed and increase the resolution of numerical results.
