摘　　要：In this paper,the wrinkle-crease interaction behavior of a rectangular membrane under edge tension is simulated.The creased membrane is modeled by using a Modified Two-Parameter model.In this model,two crease parameters,i.e.the effective modulus of creased membrane and the residual stress from creasing,are computed by using MacNeal's method that was firstly applied directly in a flat membrane with the local crease.We have proposed a method to solve the wrinkling computing issue of the creased membrane by using a Direct Perturb-Force technique in our previous work.Based on our method,the effects of crease location on the wrinkle-crease interaction behavior can be evaluated accurately.These results will be of great benefit to the analysis and the control of the wrinkles in the membrane structures.In this paper, the wrinkle-crease interaction behavior of a rectangular membrane under edge tension is simulated. The creased membrane is modeled by using a Modified Two-Parameter model. In this model, two crease parameters, i.e. the effective modulus of creased membrane and the residual stress from creasing, are computed by using MacNeal＇ s method that was firstly applied directly in a flat membrane with the local crease. We have proposed a method to solve the wrinkling computing issue of the creased membrane by using a Direct Perturb-Force technique in our previous work. Based on our method, the effects of crease location on the wrin- kle-crease interaction behavior can be evaluated accurately. These results will be of great benefit to the analysis and the control of the wrinkles in the membrane structures.
