Wear Assessment in High Cycle Rolling Contact Fatigue Using Semi-Analytical Approach [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 Presented paper deals with ratcheting prediction in the field of contact fatigue for the case of line contact. For the stated purposes, the wear model proposed by A. Mazzu [1] is used, which stands out for its simplicity and time efficiency. The model is

Basic concepts and models in continuum damage mechanics [PDF]
, 2007 In this paper, we present some basic elements of macroscopic modelling of damage. We then recall the general approach of continuum damage based on the thermodynamics of irreversible processes and its application to isotropic damage modelling.
