AB The Hole-Drilling method is a semi-destructive technique useful for obtaining residual stress distributions by drilling andmeasuring relieved strains. The standard for this method, i.e., ASTM E837 – 13a, is based on the Integral Method andfacilitates obtaining the coefficient matrices required to solve the inverse problem and to calculate the residual stress atdepths of up to 1.00 mm. A possible deviation from the coefficients given by this standard is searched when the piece has asmall thickness or the hole diameter is not 2.00 mm. FEM simulations are performed with the aim of analysing theseeffects and proposing new matrices, expressions and correlations for conditions outside the usual thickness and diameterlimits. A parametric sweep over a wide range of thicknesses and hole diameters has been implemented in ANSYS toestablish a consistent and automated numerical procedure for widening the applicability of the Hole-Drilling method.
