Resumen:

Using thin-shell theory and software ansys, wrinkling of planar membrane was analyzed in this paper. With the initial defects on the top long side of this membrane obtained form the result of the eigenvalue buckling analysis, the initial pre-stress of planar membrane was determined. Based of it, given different level shears, different pre-stresses will receive, then different wrinkling will emerge on the planar membrane. These results show that pre-stress of membrane is the important factor to the wrinking of planar membrane.
