Experimental and Numerical Investigation of Flash-butt-welded Joints in Pearlitic-steel Rails: Fatigue and Residual Stress

Experimental and Numerical Investigation of Flash-butt-welded Joints in Pearlitic-steel Rails: Fatigue and Residual Stress

This study is focused on the performance evaluation of flash-butt-welded rail joints concerning their mechanical strength and fatigue life. Residual stresses created in the heat-affected zone were measured and the effects of the welding process and notch sensitivity on the fatigue behavior in the we...
