Abstract
The large deformation of incompressible rubber cylinder under inner pressure is analyzed by a kind of new rubber materials strain energy function. The theory formulation for the displacement and stress is presented. The penalty finite element formulation is established in order to analyze nonlinear rubber materials, and the results of finite element method agree well with theoretical ones. A new method for controlling the calculating stability and convergence rates is put forward. The selection of the appropriate penalty factor and its influence on calculated results are discussed.
