Abstract:

Experimental results developed from tests of uniaxial, smooth specimens obtained from the head of an unused section of rail have been reported. Testing encompassed a broad range of conditions - monotonic tension, monotonic compression, and fully reversed constant-amplitude strain cycling. Additionally, a study of 'history effects' was made. Included in this study were tests to examine the influence of orientation, mean stress, initial prestrain, and periodic overstrain (both the cyclic deformation response and the fatigue resistance being reported for each condition). Results obtained from the above tests were used to develop mathematical models for rail deformation response and failure. Particular attention has been paid to the influence of stress state on deformation response and fatigue resistance.
