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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license.
