Kurzfassung:
In the previous paper, the authors described a mathematical model of the process, this paper is devoted to the issues of modeling and analysis. The effects of different parameters such as temperature gradients, membrane’s aspect ratio, pre-stress, thickness, anchor points, and elastic properties of the membrane and the multilayer on the characteristic wrinkling behavior (wavelength, size, critical load and location) have been examined. It is found that the critical buckling condition of the membrane is dependent on the compressibility, anchor points, aspect ratio and the thickness of the membrane, and it’s out of plane displacement depends on the magnitude of the applied in-plane tension. The number of wrinkles decreased with increasing the number of anchor points of the membrane. An effective active flatness control method is used to minimize the surface error (RMS error). Also, it is seen that the multilayer geometry helps in reducing the surface error of the membrane structure.
