Paper Abstract

Theoretical and experimental investigation into the use of the holographic blind-hole method to measure residual stress is presented in detail. Under the specific optical configuration proposed in this paper, both maximal and minimal out-of-plane displacements can be directly obtained with a single axisymmetric measured fringe pattern. To increase the displacement measurement accuracy in order to facilitate the residual stress measurements of high strength/high stiffness materials, a phase-shifting technique was introduced into the hologrpahic setup. After careful data analysis and error analysis, the residual stress obtained experimentally was found to agree well with the theoretical residual stress results.
