Wrinkling suppression in thin film using position distribution of microstructures
Source abstract
Abstract
Thin film structures will be wrinkled due to buckling deformation under the influence of compressive stress. The wrinkle and tension states of the thin film can be changed by introducing microstructures. So we introduce rigid elements on the thin film to suppress the wrinkling behavior of the thin film, and propose a method to calculate the optimal distribution position of the rigid elements on the thin film. Using this method, the optimal distribution positions of the square rigid elements on the biaxially stretched square thin film were calculated, and the effectiveness of introducing rigid elements on the thin film to suppress the wrinkle was verified through numerical simulation and experimental research. The results show that the wrinkling behaviour of the film can be effectively suppressed by placing rigid elements at the optimal position obtained by the method proposed to this paper. Our findings could provide new design ideas for thin-film antenna structures in aerospace engineering.
