In this paper, a wrinkling algorithm is described to simulate realistic wrinkles on the membrane for large computational overheads. The membrane has very little in-plane deformations and most of the deformations come from buckling. The formulation of the deformed area due to symmetric loading uses the modulated method to ensure or characterize the user defined wrinkle pattern which is based on deformation of individual triangle. The methodology facilitates the use of small in-plane deformation stiffness's and a coarse mesh for the numerical simulation. This approach has been validated using the numerical simulation considering the different symmetric loading condition on the particular triangular shaped element. Moreover, the ability to design wrinkles (even on generalized deformable models) makes this method more versatile.
