Originální abstrakt

The hole drilling method is widely used for residual stresses measurement. The evaluation of the inhomogeneous residual stresses through the depth can be performed by the integral method or power series method. The calibration coefficients are necessary to determinate by the finite element method for each method separately. The determination of the calibration coefficients takes usually much time. The generally view of the residual stress determination gives the influence function. The problem of the influence function solved Beghini (2000). The calibration coefficients for the integral method and for the power series method and for an arbitrary new method can be determined by the influence function. The base of the integral method consists in the approximation of the residual stress by a piecewise constant function. The base of the power series method consists in the approximation of the residual stress by a polynomial function. The new method would be consisted in an approximation of an arbitrary function. In this paper the influence function is determined for the strain gauge rosette RY 61 S. Then the influence function is used for the residual stress determination. Further the calibration coefficient of the integral method was compared with the calibration coefficients determined by the influence function which was provided with kindness by M. Beghini from University of Pisa, Italy.
