A recent paper by H L Pang and S R Pukas 1 touched on some important aspects of non‐uniform residual stress measurement by the hole drilling method. This note discusses three significant issues raised in that paper, and presents a dissenting viewpoint. The three issues concern: the reliability of calibration constants derived from finite element calculations, the choice of basic stress calculation formulations, and methods used to compute the residual stress variation with depth from the specimen surface.
