Paper Abstract

One of the widely used methods for determing residual stresses is hole-drilling. in which the radial strains proGJced when residual stresses are relieved by the hole and are meutred by differem experimerUJ tedniques, including the holographic interferomeby. Jn this paper a superposed holosraphic interferometer is used to determine in-plane radial displacemera cbs to releasing of residua1 atreues by hole-drilling. 1be tam •superposed holographic interferometer' denotes the assembly of the object 81.rlace section and holographic plate in an immediate vicinity to the object. With the purpose of raising the interference patterns comut the hiah-frequency gratiqJ is used. Residua1 stresses are obtained by the bomdary i!Ugral equations method. Jn this method the distribution of interference fringe orders along the 2-3 concentric holes is used for determine the bomdary conclitions. The combined e111<loyment of holowaphic interferometry and bomdary i!Ugral equations method allows to calculate the residual stress clistribution along the hole's round and inside this region too. ~ between stress holographically determined with a COl11JUled value is satisfactory.
