| Summary |
The finding an equilibrium configuration of membrane structures is one of problems including strong geometrical nonlinearity， and many research papers have been published. However the static and dynamic analyses of inflation and deflation of hyperelastic membranes have been limited.
This paper deals with the inflating and deflating mechanism of a hemisphere membrane due to air pressure by using an isoparametric membrane element. The nonlinearities arising from large displacement，from nonlinear stress-strain relationships and from neoconservative loanings are considered. The snapthrough behavior and the difference between inflating and deflating mechanism of the membrane are verified. The dynamic behaviors of the membranes under the action of impact pressure are also investigated.
