Summary on Grant Application Form |
|
Fatigue crack propagation is associated with complex crack tip stress fields which control the mechanisms of crack advance. In order to develop new materials with improved fatigue resistance and to predict fatigue life more accurately, a better understanding of the interactions and interrelationship between the microscopic and macroscopic components of the stress field and the microstructure at the crack tip is required. It is the aim of this project to measure the crack tip stress field in advanced metal matrix composites directly and non-destructively using neutron diffraction. The effects on the stress field of macroresidual stresses, interphase stress and, for continuous composites, crack bridging will be investigated. These direct measurements will then be used to examine the validity of current predictive models.
