elastic-hyperelastic

Hi All,

 I am trying to model the inflation of an enclosed elastic cylinder. The only example I have came close to in the Abaqus support documentation is the air bag inflation test. However, even reading the documentation, I am still unsure on how to model the airbag before an inflation force is applied. Can someone help me with this? You can also e-mail directly: manpreet.puri@strath.ac.uk.

Any help would be much appreciated and thanks all for your time to look at this post :)
