Estimation of Wrinkle Amplitude on Square Membrane under Corner Tension Loads Using Tension-Field Solutions

Abstract

Recently, large space structures using thin films have attracted widespread attention. Finite-element analysis using tension-field theory is expected to be a practical tool for analyzing a nonlinear wrinkled-membrane behavior in large space structures with low computational cost. Aiming to extend functionality of wrinkling analysis using tension-field theory, a simplified formula capable of estimating a wrinkle amplitude using tension-field solutions was proposed in past research. In the current study, we investigated the applicability of that proposed formula to the wrinkling behavior on a square membrane subjected to corner tension loads.
