Abstract
Multilevel rotating‐bending block tests were performed and the effect of stress peaks on the damage sum of notched aircraft material specimens was investigated. Test results were compared from the viewpoints of the residual stress concept and of the non‐linear, stress‐dependent damage‐cumulation approach.
The residual stress concept seems to be valid not only for nonsymmetrical axial loading but also for some rotating‐bending loading sequences, when stress peaks are acting. The non‐linear stress‐dependent damagecumulation approach is in good qualitative agreement with rotatingbending test results, in the case where the role of residual stresses is negligible.
