Sažetak
The objective of this paper is to examine the effects of measurement error on residual stresses evaluated with the Hole drilling and Integral Method calculation. A detailed analysis of causes and magnitudes of strain measurement error is beyond the scope of this paper. The indicators needed for the error estimation and depth increment distributions with respect to systematic and random errors are discussed. It is shown that the maximum attention must be devoted to random errors. According to presented result it was concluded that practically no more than three points of residual stress distribution can be calculated.
