An experimental and numerical study on wrinkling phenomena of a membrane are carried out. Shapes of initial and deformed states of a square membrane are messured precisely using CCD Laser Displacement Sensors. To obtain the quantified wrinkling behavior with displacement field, geometrically nonlinear analysis with MITC (Mixed Interpoloation of Tensorial Components) shell elements is conducted. Using a spectrum evaluation method based on two dimensional fast Fourier transform, overall behavior of the square wrinkled membrane, which are obtained from the experiment and numerical simulation are compared. It is shown that the experimental and numerical results are in good agreement. In addition, the importance of the boundary condition and gravity effect in the wrinkling analysis is clarified.
