Аннотация:Numerical evaluation of the reliable measurement range of residual stresses by probe-hole method is obtained using the finite element method. It is demonstrated that recovery of the ratio of components of the stress state when using the approach based on basis functions is performed with accuracy sufficient for practical application. Precise recovery of values of the components of the stress state is possible with the effective intensity of residual stresses in the range of 0–0.7 of the tensile yield of the studied material.
