Supplementary material: MATLAB Database Variable Amplitude fatigue tests in reference "Validity of high cycle variable amplitude lifetime estimates of steel welded joints using design models"
Abstract
This supplementary data contains a .mat file of the variable amplitude fatigue test database of steel welded joints uses for the publication "Validity of high cycle variable amplitude lifetime estimates of steel welded joints using design models" submitted to SEI Journal. The variable amplitude fatigue test data is obtained from sources of other authors and reconstructed for the purpose of this database. Please see the SEI publication for the references to the original papers.
