Abstract
The dynamic behavior of a wheel-rail system was investigated. The Melan's (lower bound) shakedown theorem was applied to calculate the shakedown limits. The preliminary research results indicate that the short wavelength corrugation of the rail is due to a large amount of energy delivered from the vibration components at high frequency. The finite element analysis of the wheel-rail contact shows that the maximum stress under the subsurface exceeds the first yield strength, which leads to plastic deformation.
