A model for predicting plastic strain and surface cracks at steady-state wear and ratcheting regime

, 2018
Unidirectional plastic strain accumulation (ratcheting) is one of the main causes of surface crack nucleation in rails and wheels in dry condition. It is related to frictional forces which develop at the contact interface due to sliding, especially in ...
