Institution National Aerospace Laboratory NLR Date 1979-11-30 Abstract The report describes a joint Garteur activity in the field of the prediction of crack propagation under variable amplitude loading. Existing crack propagation models or models under development will be checked with NLR crack propagation data of 202U-T3 Alclad 2 mm sheet material under F-27 Spectrum flight simulation loading. After completion of model checking follow-on activities will be defined. The report includes also the NLR database, consisting of constant amplitude data, F-U spectrum data and F-27 spectrum test results. Also given is the F-27 Spectrum load generation program.
