Fretting Fatigue Testing
Fatigue fretting is the process of crack formation and progressive crack growth at a location in a mechanical system where two components are in contact and undergoing a vibratory loading. A new ASTM International standard provides insight on what conditions promote fretting fatigue and offers approaches to design an experiment to assess it.
E2789, Guide for Fretting Fatigue Testing, was developed by Subcommittee E08.05 on Cyclic Deformation and Fatigue Crack Formation, part of ASTM International Committee E08 on Fatigue and Fracture.
“There are no standards for conducting and analyzing fretting fatigue tests,” says Richard W. Neu, Ph.D., professor of mechanical engineering, Georgia Institute of Technology, and a member of E08.05. “This guide serves as a starting point for someone who desires to evaluate the fretting fatigue response of two materials in contact.”
Neu says that E2789 will be useful to researchers interested in developing a program dealing with fretting fatigue and fretting wear.
