The design of a component and its durability can be improved and assured to a great degree by means of a specific setting of its residual stress state. This is referred to as stress engineering. Prime examples of this are gear wheels (Townsend 1992,

There is a strong need for reliable residual stress measurements. On the one hand, residual stresses can be beneficial, when they are adapted to external loads. On the other hand, they can be detrimental, when they are unknown. Thus, their occurrence

The incremental hole-drilling method is the method of choice to determine residual stress depth distributions with limited costs and minor destruction of the investigated component. With a spatial resolution of commonly two millimeters in diameter an

Residual stresses are always present in nearly every component as a consequence of the manufacturing process. If the material exhibits a crystalline structure, diffraction methods are undoubtedly a method of choice for residual stress analysis. Howev

For the analysis of residual stress depth distributions the semi-destructive incremental hole drilling method is the process of choice for quick and cost-efficient measurements. Nevertheless, the experimental execution has to be carried out carefully

Due to the fact that no analytical solution exists to determine residual stresses in components with geometrical deviations from an ideal plate with the well known semi-destructive incremental hole-drilling method, calibration functions are required.
