  • To determine the residual stress, concentrated forces instead of distributed stresses, are assumed to be released around the hole drilled through. Concentrated forces are consisted with pairs of concentrated farces which have opposite directions and small distances. Residual stress determination on assumption of concentrated forces is compared numerically with normal method based on Kirsch's solution and proved to be available when released strains are measured at a little distance.
