Summary on Grant Application Form |
|
Shot peening is a manufacturing process applied to notched zones of engineering components in order to both increase fatigue limits and fatigue endurance. Fundamental knowledge on how this is achieved is totally lacking, only experimental empiricism exists and so no science-based information is available to engineers on how lifetime can be optimized by intermediate peening during the lifetime of a component or how mixed surface treatments might be introduced to improve surface resistance and extend component lifetimes.This proposal is to employ the new science of microstructural fracture mechanicsm, with aid of the SIRIUS scanning acoustic microscope, when studying initiation, Stage I and Stage I-to-Stage-II transition fatigue crack growth phases. It is these phases which dominate the resistance behaviour of materials and the lifetime of shot-peened engineering components.
