Inflation of a Spherical Rubber Balloon

Application ID: 12599


This model aims to investigate the inflation of a rubber balloon with different hyperelastic material models, and compare the results to analytical expressions.

A controlled inflation could benefit clinical applications, cardiovascular research, and the medical device industry, thus the importance of understanding the hyperelastic behavior during balloon inflations. The example is taken from the book “Nonlinear Solid Mechanics”, by G. Holzapfel.
