| Summary |
This research addresses wrinkle distribution of the square membrane structure by tension loads applied at corners. The measurement system is built as the square membrane set in upright position and the wrinkle distribution 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 wrinkle measurement results, the significant factors that give rise to difference between analysis and experiment is discussed to develop an accurate wrinkling analysis model.
