Ring-Core Residual Stress Measurement: Analysis Of Depth Increment Distribution For Integral Equation Method

Popis výsledku v původním jazyce

The ring-core method is the semi-destructive experimental method. Correctly determined and properly used calibration or relaxation factors for the residual stress measurement by the ring-core method are essential. Knowledge of their dependence on the geometric changes of the ring-groove and on the disposition of the residual state of stress through the depth of metallic material gives results, correspond of theirs appropriate application. This paper is focused on the evaluation of calibration factors aij and bij, necessary for the residual state of stress determination by the integral equation method. The finite element method is used for simulation of the residual state of stress and to calculate relieved strains on the top of the core. Three types ofthe depth increment distribution are studied, i.e. constant, increasing and optimized depth increment distribution, which is commonly used.
