Summary on Grant Application Form |
|
The general aim of this project is to investigate the influence of shot peening on fretting damage mechanisms and integrate the effects of shot peening with structural assessment procedures for fretting fatigue, as displayed in high load transfer joints. The research programme is designed to develop an understanding of the influence of fastener clamping force on the failure initiation mechanism and fatigue life of high load transfer joints. This will be achieved by carrying out tests (i) to study mixed-mode crack propagation, with loads that are representative of actual fretting conditions. Mixed-mode crack growth rules will be developed. (u) Fretting tests performed to differentiate between the fretting conditions associated with pre-loaded bolt assemblies.The results will be used to assess the fretting crack growth models developed in the current programme. New methods of fretting fatigue life prediction embodying the main phases of fatigue crack growth, including initiation, microstructurally short, physically small and long cracks, will be developed.
