• Abstract:
  A finite element formulation for shakedown stress analysis of rail vehicle wheels is presented, based on a hypothesis that the shakedown state is axisymmetric. The method can be used to estimate shakedown stresses in wheels subjected to combined mechanical (wheel/rail contact) and thermal (temperature gradients and thermal stress due to braking) loads. The formulation includes provisions for initial manufacturing stress, shifting contact locations, and temperature-dependent material properties. Validation results and demonstration example analysis of an actual wheel design are presented.
