Analytical modeling of membrane bending in range of large deflections

In early stage of the design process, modeling is a crucial phase as it allows the designer estimating the device performance. Very often, this phase is time-consuming, especially when FEM simulator is used. Hence, a fast and reliable method is desirable. Moreover, in case of simple structures which behavior is described with quite simple equations, the use of analytical model is obvious. In this paper we present a complete model of a membrane bending in range of large deflections that has been developed using FEM simulations.
