| Summary |
An optimum boundary design to minimize wrinkle intensity of a square membrane is investigated. The wrinkle intensity in a partly wrinkled membrane is evaluated from an apparent strain energy resulting from the deformation through wrinkling. This wrinkle intensity is used as an objective function for wrinkle reduction. As a numerical example, the taped regions around the boundary of square membrane are designed to minimize the wrinkle intensity. The numerical result shows that most wrinkles are eliminated by the optimization that is confirmed by the shell model analysis.
