Inflation of a Spherical Rubber Balloon
Application ID: 12599
This model demonstrates the inflation of a rubber balloon with four different hyperelastic material models. The results are compared with the analytical solution for a thin-walled, spherical vessel.
Controlling the inflation of hyperelastic balloons is important in clinical applications, cardiovascular research, and the medical device industry. The example is taken from the book “Nonlinear Solid Mechanics”, by G. A. Holzapfel.
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:
- COMSOL Multiphysics® and
- Nonlinear Structural Materials Module and
- either the MEMS Module, or Structural Mechanics Module
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 Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
