Modeling of vertical split rim cracking in railroad wheels

Damage evaluation regarding to contact zones of high-speed train wheel subjected to thermal fatigue

“…Masoudi et al developed three-dimensional finite element analysis for the simulation of fatigue crack growth in mono-block wheels [28].Venkata and Sankaran described that the residual stresses that develop during both the manufacturing process and under service conditions are estimated using decoupled thermal structural finite element analysis (FEA), and are considered as initial stresses for the vertical split rim cracking analysis [29]. Gordon et al used FEA methods to simulate wheel quenching and tempering processes and were able to quantitatively describe the resultant state of stress throughout the wheel cross section.…”

Influence of wheel out‐of‐roundness on the remaining life of railway wheels under mixed‐mode fatigue loading

“…Continuous crack expansion can cause wheels to fall off and endanger the safety of trains. [1][2][3][4] Wheel rim cracks may cause very-high-cycle fatigue under rolling contact loading, with the crack initiation site at a depth range of 10-25 mm from the tread surface. 5 The large brittle inclusions in this part are one of the primary causes of wheel rim cracks.…”
