The Large Deflection of the Orthotropic and Rectangular Membrane under the External Distributed Load

This paper reviews research on the large deflection of the orthotropic and rectangular membrane under the distributed load. Through building the theoretical model of the orthotropic and rectangular membrane under the distributed load, the authors deduce the equations set of the membrane which has the effect of pretension and solve the equations set with the perturbation method. The authors obtain the relational expression between the maximum deflection of the membrane’s centre point and the external load, then make a comparison between the large deflection and the small deflection. At last, With the example, the authors analyze the change of the deflection of the centre point of the membrane along the external load, and the length of the side, and the large or small of the pretension and other parameter.
