Abstract:Combined with hole-drilling method,the method of large shearing amount speckle in- terferometry is proposed to measure residual stress in a specimen is measured and the result agrees very well with that obtained theoretically.In addition two-dimensional residual stresses on the surface of a real structure are also measured.
Keywords:large shearing amount speckle interferometry  liquid optical wedge  hole-drilling
