Abstract

Recent developments have shown that strains measured on the surface during an incremental drilling can be related to residual stress distribution. Researchers throughout the world have proposed different methods of calibration which lead to more or less accurate results. This paper discusses different approaches used. The variation of the strains measured on the surface for each increment is due to two causes, first the residual stresses in the layer and second, the change of the hole geometry. Most authors do not consider the latter phenomenom. Our results show that this causes a significant error in the experimental data. Finite element method has been used for the computation of the coefficients for all types of strain gauge rosettes when the hole diameter is fixed.
