Originální abstrakt

One of the most used methods for measurement residual stresses is the hole-drilling method. This method is based on drilling a small and shallow hole. If the residual stresses are present then the strain releases, which is usually measured by means of strain gauge rosette. The residual stresses from the strains obtained this way, we can determine by the help of derived equations. In these equations exsert calibration coefficients, which represents a relation between relaxed strain and residual stresses. These coefficients, which are functions to many parameters, is necessery to determine in advance. It is possible to determine them by several ways: analytically, numerically (for example through the finite element method: FEM) and experimentally. This article deals with determination of this coefficient numerically by the FEM for measurement of residual stresses which are uniform by the depth for the strain gauge rosette RY 61 S.
