INTRODUCTION TO STRESSES IN RAILS: STRESSES IN MIDRAIL REGIONS

The results of an extended analysis of the stresses in rails are summarized as an introduction to the mechanisms that drive rail flaws to failure. The mechanics of rail flexural, thermal, contact, and residual stress development are discussed in terms of the distribution of stresses in the rail, the stress cycles that occur with wheel passage, and their relationship to the propagation of typical midrail flaws. These analyses are limited to continuously welded rails and the regions of bolted-joint rails that are outside of the influence of the rail joints.
