Abstract

A review is made of procedures, developed at the National Aeronautical Laboratory for fatigue crack propagation testing under flight spectrum loading. They include K-control and on-line spectrum editing that were found to have a significant impact on spectrum load testing. Techniques are described for unambiguous assessment of crack closure stress and for binary-coded marker loading.
