Abstract
The application of a new apparatus for the mechanical analysis of residual stress is described; this enables the determination of the distribution of residual stresses of the first kind over the cross-section of bar-shaped specimens. Results of residual stress analysis on heat-treated specimens of heat treatable steel 42CrMo4 (1.7225) are presented and compared with those from the X-ray diffraction method and the incremental hole drilling method. The residual stresses measured by the X-ray diffraction method at the surface agree well with the results of the layer removal method, whereas in this case incremental hole drilling led to erroneous results.
