Abstract:
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.
