Rolling contact fatigue testing of peek based composites

Rolling Contact Fatigue in Ultra High Vacuum

Analysis of Surface Crack Growth under Rolling Contact Fatigue

Understanding the fatigue crack growth phenomenon in railheads requires a study of driving forces such as the crack tip opening and sliding displacements, under repeated rolling contact. Finite element simulations, allowing elastic-plastic deformation, and mixed-mode crack growth laws were utilized to demonstrate that the fatigue crack growth rates display a minimum after a finite amount of cra...

Rolling contact fatigue of surface coatings—a review

The aim of this review is to survey the state of the art relating to the rolling contact fatigue (RCF) investigation of various overlay coatings and also, to ascertain the influence of design parameters such as the type of deposition process, coating material and thickness on the RCF performance. Rolling contact fatigue is a significant factor in the failure of components in rolling/sliding con...

Effect of Surface Morphology on Fatigue Behaviour of Adhesively Bonded Carbon Fibres Peek Composites

In this paper, experimental fatigue behaviour of adhesively bonded PEEK composite was investigated. PEEK based materials are considered as a high performance thermoplastic materials conferring to their good mechanical properties and chemical resistant for many aggressive environments due to their semi-crystallinity property. However, it is well known that the adhesive bonding assembly of this k...

Numerical Computation of Rolling Resistance Based on the Result of Tire/Road Static Contact Analysis

Among various dissipating mechanisms, the viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with improving the fuel consumption of vehicles and resultantly energy savage. Hysteretic loss is a fraction of...
