A Semi-Analytical Prediction of Wear Rate of an Inductively Hardened Wheel Steel under Rolling Contact

Abstract:

Presented paper deals with ratcheting prediction in the field of line rolling contact. The main aim is to simulate the wear process due to the contact fatigue on inductively hardened sample of R7T material. For the stated purposes, the authors have used the wear model based on shear band cracking mechanism and non-linear kinematic and isotropic hardening rule of Chaboche and Lemaitre. Obtained results are subsequently compared with experimental data as well as with metallographic analysis.
