Numerical Simulation and Experimental Validation of the Inflation Test of Latex Balloons

Abstract

Experiments and modeling aimed at assessing the mechanicalresponse of latex balloons in the inflation test are presented. Tothis end, the hyperelastic Yeoh material model is firstly characterizedvia tensile test and, then, used to numerically simulate viafinite elements the stress-strain evolution during the inflation test.The numerical pressure-displacement curves are validated withthose obtained experimentally. Moreover, this analysis is extendedto a biomedical problem of an eyeball under glaucoma conditions.
