Abstract: Releasing coefficient is one of the most important index when applying hole-drilling method to measure residual stress.In this paper,the effect of the position of strain gages and the depth of drilled hole on the releasing coefficient are studied by using the finite element method (FEM),and the corresponding fitted curves are acquired.Compared with the previous research results,the method and results discussed in this paper is valid.
Key words: hole-drilling method, residual stress, releasing coefficient
