New information about incremental strain method used for residual stress measurement by ring-core method


Abstract eng:
This paper follows up an article Analysis of Calibration Coefficients of Incremental Strain Method Used for Residual Stress Measurement by RingCore Method (Civín, 2010), where the values of the calibration coefficients and have been determined in dependence on the depth of drilled hole and on the disposition of the residual state of stress. Influence of blunting the cutting tool during drilling process is taken into account and new calibration coefficients are compared with the common ones, which are determined without radius at the bottom of the annular groove. Evaluation of relaxed strains by integration across the strain gauge´s measuring grid is considered too.
