Abstract: | Large strain fixed-end torsion of circular solid rubber bars is studied semi-analytically. The analyses are based on various
non-Gaussian network models for rubber elasticity, some of which were proposed very recently. Results are presented in terms
of predicted torque vs. twist curves and axial force vs. twist curves. In some cases, the predicted stress distributions are
also given. The sensitivity of the second-order axial force to the employed models is considered. The predicted results are
compared with experimental results found in the literature. |
