Determination of Residual Stresses in Cylindrical Components by the Hole-drilling Method

Popis výsledku v původním jazyce

Background The hole-drilling method is a widely used technique for the determination of residual stresses, but the application of the method requires a planar surface of the measured component. Objective Since many components have a cylindrical surface in industrial practice, this study focuses on the determination of residual stresses in cylindrical components. Methods Several cylindrical bodies with various residual stress states were simulated and the method described in ASTM E837 standard was used for the evaluation process. In order to properly simulate the required residual stress states in cylindrical bodies, a new approach for the application of load into the finite element models of hole-drilling experiment is presented. Furthermore, a new procedure with four sets of calibration coefficients is proposed to determine the uniform residual stresses in cylindrical bodies. Results Based on the obtained results, the factors affecting the evaluation are identified and the errors of residual stresses evaluated by ASTM E837 standard are quantified for several cylindrical bodies. Moreover, the testing of the procedure with four sets of calibration coefficients shows a negligible relative error of the evaluated residual stresses even for cylindrical bodies with a small radius. Conclusions It can be stated that the proposed procedure significantly improves the evaluation of the uniform residual stresses in cylindrical bodies. The results of this study can also be used to estimate an error in practical measurements or to determine the radius of a cylindrical body, which is still acceptable when the residual stresses are evaluated by ASTM E837 standard.
