Wrinkling analysis of square space membrane structure under corner tension forces
摘要
Abstract
An analytical approach based on the bifurcation theory is presented, in which the wrinkles are trea-ted as the local buckling phenomena of the elastic thin plate with little bending stiffness. The average wrinkling wavelength was determined by incorporating the stress field and the out-of-plane force equilibrium condition of the wrinkled membrane. The wrinkling amplitude was then obtained by associating the characteristics of wrink-ling texture with the obtained wrinkling wavelength. Results reveal that the wrinkled pattern exhibits a noticea-ble difference when the tension load is changed gradually, and two wrinkling styles are identified. The first style occurs for symmetric and moderately asymmetric loading, and it is characterized by small, radial comer wrin-kles; the second style occurs for strongly asymmetric loading and is characterized by a deep, large diagonalwrinkle. The analytical predictions on the wrinkling characteristics and the developed rules are validated against wrinkling experimental observations.关键词
