What is Rail Wear Limits and Strength Analysis about?

This document summarizes an analysis of rail wear limits based on investigations of rail strength. The analysis considers two failure modes: permanent plastic bending and rail fracture. Rail bending stresses are calculated using beam theory on an elastic foundation. The effect of wear is modeled as geometric changes to the rail cross-section from material loss. Wear patterns examined include vertical head height loss and side wear of the gauge face. An elementary plastic collapse criterion is used to estima
