... examination of the crack origin revealed that casting pores played a role in initiating the crack. Stress components, identified by finite element analysis, also played a role, particularly the stresses imposed by the bolt assembly leading to plastic strain. It was concluded that the failure can be prevented...

..., it was recommended that welding repair be curtailed; welding could exacerbate the cracking problem by introducing additional residual stresses into the rail. Existing through-flange cracks were analyzed by a finite-element method to show that the cracks did not compromise the integrity of the rail. However, because...
