Multi-axial fatigue analysis of aluminothermic rail welds under high axle load conditions
International Journal of Fatigue, 2011Abstract Fatigue crack initiation analysis is performed at the edge of the weld collar of an aluminothermic weld, in order to examine one of the failure modes that occur in this weld type under high axle load conditions. Since the stress state is multi-axial and the stress history involves rotating principal stresses, a shear based multi-axial ...

The effect of geometric features on multi-axial fatigue behaviour of aluminothermic rail welds
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2011Aluminothermic rail welds typically exhibit a variable and often inferior performance when compared with flash butt welds. Fatigue failure as a result of surface defects or harsh geometric features in the presence of high axle loads and tractive forces gives rise to the so-called straight break and horizontal split web fractures.

This thesis seeks to improve residual stress measurement techniques in large components with complex geometries using neutron diffraction. In this work, residual stresses in rail weld samples were measured at locations in welds where traditional methods of measurement are not able to access.
