Determining the angles of squat cracks via CT scanning and metallographic observations

This study investigates the angles θ₁, θ₂, and θ₃ that squat crack faces form with respect to three orthogonal planes: the rail top, the longitudinal-vertical cross-section and the lateral-vertical cross-section. Rail samples with squats of various severities are obtained from the field. Their three...
