Fluid pressure loading of a hyperelastic membrane

摘要

This paper examines the problem of the fluid pressure loading of a hyperelastic membrane made of a natural gum rubber, that is fixed along a circular boundary. The fluid pressure loading of hyperelastic membranes have several important technological applications particularly in the area of bio-medical engineering and the response of the membrane to fluid pressure loading can be useful in identifying the applicability of the various forms of strain energy functions that are proposed in the literature for describing hyperelastic behaviour. The results of the fluid pressure induced deflected profiles of the circular membrane together with computational modelling of the experiments are used to identify the range of applicability of several forms of strain energy functions for the hyperelastic materials.
