| Summary |
An experimental and numerical study were carried out for investigating validity of a wrinkling analysis with MITC (Mixed Interpolation of Tensorial Components) shell elements. Wrinkling phenomena of the square membrane, held fixed at three corners and subjected to in-plane shear force at the remaining corner, were investigated. Comparing the simulation results to experimental ones, effectivity of the wrinkling analysis conducted was shown, and it was quantitatively clarified that imperfection of the fixed boundary condition in the experiment affects the surface configurations of the wrinkled membranes. In addition, effects of the loading sequence of gravity on the wrinkling analysis were also presented.
