Thermomechanical wear modelling
Tribotest, 1994AbstractIt is assumed that the contact between bodies in sliding motion produces a stress field and frictional heat source that may induce severe wear from material yielding or fracture. For this situation, a thermomechanical wear model is used to develop a wear transition equation for identifying the dominant factors that will reduce or control such ...

Journal of Adhesion Science and Technology, 1990
From a fundamental viewpoint, adhesive wear must be related to the cohesive strengths of the contacting materials and the adhesive strength of the interface. These quantities are related to the electronic structures of the specific atomic species involved. Using an energy balance approach, an expression has been derived which permits calculation of the

Journal of Applied Physics, 2020
The classic sliding wear model, represented by Archard's equation, has long been used to estimate the service life of equipment and guide selection and modification of tribo-materials. However, the model was developed based on the asperity contact geometry without directly dealing with the wearing energy, rendering it unable to precisely describe wear ...

Corrosion Science, 1993
Abstract Many models are now available which may form the basis of a predictive tool to describe ductile, brittle and scale modified erosion processes. From a review of these models, it is clear that a unified approach is required, incorporating aspects of many of these models, if erosive wear both at room temperature and elevated temperature is to ...

Wear, 1962
Abstract The wear produced between two metallic bodies sliding relative to each other has been correlated with stress. The results of 1,200 tests for various combinations of materials and lubricants have shown that wear can be eliminated for a given amount of time if the shear stress is kept below, a certain fraction of the yield point in shear of ...

On the modeling of mechanochemical wear
Journal of Friction and Wear, 2012The paper deals with the mathematical modeling of mechanochemical wear. The classification of tribocorrosion models is analyzed and the advantages and disadvantages of each model type are discussed.

Wear, 2005
The abrasive wear rates of materials may be very simply related to their mechanical properties, provided wear takes place under very simple conditions. However, wear rates in many practical situations can be controlled by effects which either relate to mechanical properties in more subtle ways, or which are controlled by quite different parameters ...

Diagonal Wear Predicted By a Simple Wear Model
1986Diagonal wear on tires is a significant problem that can cause noise and vibration, and reduce the useful life of the tire. A wear model is used to show how diagonal wear can develop across the tread under certain conditions of toe and camber on a nondrive axle.

Abstract A nonlinear wear model for a cylinder rolling over a periodically varying surface is derived from the theory of half spaces. The model describes how some irregularities on the surface are amplified whereas others are levelled out as the number of cylinder passages increases.
