Development of a Computational Method of Low Cycle Fatigue Prediction for Multi-Layer Surfaces under Rolling/Sliding Contact Conditions 2007-01-0388

The application of tribologically enhanced coatings to automotive components is increasingly common. This paper highlights the development of a computational method used to simulate multi-layer coatings subjected to repeated mixed rolling / sliding contact.
Through simulation with ABAQUS and the application of a specially written external subroutine, the simulation method monitors the stress and strain states during the simulation against a number of criteria used to locate the point of material failure.
The results from a number of rolling contact with coated samples are used to verify and refine the user subroutine with the aim to developing an accurate RCF prediction method.
