Description

The potential for crack initiation at a surface-breaking defect is strongly dependent on the radius of curvature p at the defect root: a small radius can lead to large stress concentrations which greatly increase the risk of crack initiation. In this project, the objective is to develop a technique for estimating the radius of curvature at the root of a fretting wear defect on the inside surface of a CANDU nuclear reactor pressure tube.
