ON THE EXPANSION OF A DEFORMED CYLINDRICAL ELASTIC MEMBRANE

In the present note we consider the effect of radially expanding one e nd of a cylindrical elastic membrane that is also subjected to longitu dinal extension coupled with a twist. In doing this we start with the results of Tait, Steigmann and Zhong who studied the extension and twi st of a cylinder with fixed end radii. We use tension field theory to provide a model of the membrane in wrinkled regions giving rise to exp licit analytic solutions within these regions. Elsewhere we rely on a numerical scheme to provide graphical results which are displayed for various quantities of interest.
