A non contact whole field shape measurement using the grating projection method was performed to visualize formation and dissipation processes of the wrinkling phenomena on thin membranes, and their nonlinear mechanical properties were discussed. The wrinkling phenomena in a rectangular polyimide film, which held fixed at the bottom side and subjected to loadings at the upper side, was treated. The measurement results showed that the nonlinear wrinkling behavior such as the snap through phenomena appeared in the formation and dissipation processes of wrinkles was successfully captured. Through the discussion on the dissipation processes of wrinkling phenomena, the conditions of the applied tensions to reduce the distortion of the membrane surface feature are presented.
