Abstract

We consider the inflation of an axisymmetric polymeric membrane.Some membranes composed of viscoelastic materialsdescribed by a Mooney-Rivlin model show a monotone increasingpressure during inflation. These materialsdevelop a homogeneous membrane thickness in agreement with the Considere-Pearson condition.Molecularly based models such as the neo-Hookean, Doi-Edwardsor Pom-Pom models, as well as the network model recently proposed byMarrucci, exhibit a pressure maximum when inflated. Membranesdescribed by these models develop local thinningwhich may lead to bursting in finite time.Chain branching is found to stabilize the inflated polymer membrane.
