| Abstract: | Hole-drilling method is a major way to measure residual stress. In this paper the values A and B given in 2] and 3] are investigated. In the errors caused by sticked strain rosette and drilled hole are concerned. These fomulae are easy to use. The results obtained show that the errors of using these formulae are within 10%. |
