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