Abstract
This research addresses wrinkle measurement of the square membrane structure under tension loaded at each corner. Wrinkle distribution of a square membrane set in upright position is measured by using laser displacement sensor that is set at a horizontal-vertical stage composed of linear actuators. On the other hand, numerical solution is evaluated through geometrically nonlinear finite element analysis using MITC(Mixed Interpolation of Tensile Components) shell elements. In comparison of numerical results with experimental wrinkle measurement results, the significant factors that give rise to difference between analysis and experiment will be identified to develop a wrinkling analysis model.
