Abstract The finite element analyses of deformation of rubber isolator in tensile, compression and shear and torsion were performed using hyperelastic constitutive model. The finite element modeling techniques for incompressible deformation of rubber was discussed in this study as well. The analysis also focused on the deformation models of rubber structures at various loading conditions and material test data that the FEA need. Compared with experimental results, the best type of material test data for filling the constitutive model of rubber isolator under three different conditions was obtained, which provided a good reference for the numerical simulation of rubber structure.
