Abstract
AbstractA method by which measured values of residual stresses in a component of complex shape may be corrected using the finite element is presented. The surface of the component is removed layer by layer and the residual stresses after removal of each layer are measured using X-ray diffraction; the correction factors are calculated using the finite element method, thereby obtaining the distribution of internal stresses in the complex component. In addition, methods of verifying the final values of the internal stresses are suggested. As examples, the distributions of the residual stresses, within several cross-sections of two types of heat treated shaft are calculated using the above method. Finally, the reliability of the results is discussed.MST/16
