Abstract

Inverse power law scaling is a widely employed methodology for the experimental assessment of fatigue damage in aerospace and automotive structures; time scaling is needed in order to compress the actual operative lifetime into a practical laboratory timeframe. A physically consistent scaling rule is here proposed for dealing with fatigue due to wideband random vibrations in isotropic linear elastic structural elements, whose fatigue behaviour can be represented by S-N curves. It is expected that this paper will give a useful contribution to the field of experimental fatigue testing, especially for complex aerospace and automotive structures.
