Compliance Functions for Near-Surface Measurement: The Body Force Approach
- 1.1k Downloads
When a crack or a cut of finite width is introduced to a surface, the release of the residual stresses on the plane of the cut leads to deformation that can be measured and used to predict the residual stress that existed on the plane before the cut was made. Since a cut of finite width is much easier to introduce than a crack, and less likely to experience face closure associated with releasing compressive stresses, it is of practical importance to obtain the compliance functions for a cut of finite width. For this reason, the approach based on a cut of finite width introduced in this chapter for near surface stress measurement is often referred to as the slitting method.
