| Abstract: |
| The mechanical constants of rubber Mooney-Rivlin model C1 and C2 were determined with nonlinear FEA and axial compression test.The procedure for determining C1 and C2 was as follows：the sum of C1 and C2 was calculated from the hardness of rubber material at first；then the compressive stress-strain curve of rubber material with different C2/C1 was simulated by non-linear FEA and compared to the measured curve；C2/C1，with which the simulated curve was well fitted to the measured one，was the real C2/C1 of rubber material，and thus C1 and C2 were further determined from the real C2/C1. |
