Variational Principle of Hellinger Reissner for Wheel Rail Steady Rolling Contact |
| |
| Abstract: | Based on the variational principle of Hellinger Reissner and using the perturbed Lagrange technology, the variational principle of Hellinger Reissner for wheel rail steady rolling contact is discussed with wheel and rail being regarded as finite elastic bodies. It provides theoretical and computational bases for more accurate numerical computation of the contact fatigue of wheel and rail. |
