Original Abstract

The paper focuses on assessment of method for non-uniform residual stress calculation published in ASTM E837-13a for case of various hole diameters. The method is an integral method which uses calibration coefficients calculated by finite element method for strain gauge rosette 1/16" and hole diameter of 2 mm. In case of using another hole diameter these calibration constants have to be recalculated by simple formula. The aim of the study was to verify this method of recalculation. Hole-drilling experiment was simulated by using finite element method and residual stresses were evaluated from obtained strains by EVAL-7 software. Simulations were done for 6 different hole diameters. From obtained results it was shown that relative error increases with varying diameter due to recalculation of calibration coefficients. This error can reach values which significantly devalue results of measured residual stresses.
