| Abstract: | In this paper studies are done on stress analysis of rubber material using two different FEA methods:penalty FEA and mixed interpolation FEA. Via introduction of penalty function and hydropressure into the matreial strain energy density function respectively, the rubber-like imcompressible hyperelastic material is analysed by FEA. Excellent numerical results are obtained, which shows the effectiveness of the method proposed. |
