Wrinkling of Cylindrical Membranes with Varying Thickness

Application ID: 105081

In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the wrinkling disappears when the internal pressure is increased.

Two wrinkling models, the modified deformation gradient approach and the relaxed strain energy approach, are used and the results are compared.

This model example illustrates applications of this type that would nominally be built using the following products:
