Summary The present paper analyzes the nonlinear deformation of fabric composite membranes under uniform internal pressure. A mathematical programming method is applied to obtain the relationship between internal pressure and membrane deformations by minimizing the potential energy. The nonlinear deformations and the corresponding stress distributions are obtained for a rectangular membrane and an elliptic membrane with various kinds of fiber orientation angles. The deformation characteristics are also analyzed for the membranes with deformation constraints by the mathematical programming method.
