Abstract

Hole-drilling is one of the most common methods for test residual stress; it is widely used to measure the residual stresses in various materials. This method provides access to the residual stress profile in the through specimen thickness. In this paper, experimental and numerical simulation are serviced in hole-drilling method, by means of measuring the relieved strains on specimen surface when drilling each depth step by step, to find some relationship between the drilling depth and the surface strain, and comparing with an identified stresses specimen to determine the residual stresses in different depth.
