Experimental evaluation of multiaxial test-tailored specifications based on Fatigue Damage multi-Spectra
Résumé
In the industrial sector, laboratory tests are frequently performed to evaluate the durability of structures under mechanical loads. These tests typically involve sequentially applied uniaxial loads, even though operational conditions are often multiaxial. To address this inconsistency, a new frequency-domain approach has been developed to generate test-tailored specifications for multiaxial vibration based on the Fatigue Damage multi- Spectrum (FDmS). This paper analyzes this procedure through experimental trials, showing the accuracy of the generated multiaxial test-tailored specifications, as well as its ability to synthesize and generate cross-correlations.
