Determination of Principal Residual Stress Directions by the Incremental Strain Method
Original language description
The ring-core method is the semi-destructive experimental method used for evaluation of the homogeneous and non-homogeneous residual stresses, acting over depth of drilled core. By using incremental strain method (ISM) for the residual state of stress determination, this article describes procedure how unknown directions and magnitudes of principal residual stresses can be determined. Finite element method (FEM) is used for the numerical simulation of homogenous residual state of stress and relieved residual strains on the top of the model's core are measured by the three-element strain gauge, turned by the axis of strain gauge "a" from the direction of the principal stress Sig1 about unknown angle "alpha". Depth dependent magnitudes of residual strains, their differences and set of known values of calibration coefficients K1 and K2 together with properly applied linear equations are used for determination of the angle "alpha" and for re-calculation of principal stresses.
