MetadataShow full item record
A series of tests have been conducted at the U.S. NAval Postgraduate School, Monterey, California, to evaluate the effects on fatigue strength caused by the superposition of two stress-raisers. The cases of reversed bending and torsion have been previously considered. This paper continues the investigation for axial tension of a thin flat plate of finite width. The stress raisers consist of a transverse hole and a groove. The predicted and experimental strength reduction factors are compared and stress-cycle curves are presented. The author wishes to express his appreciation for the advices and encouragement given him by Professor Virgil M. Faires of the U.S. Naval Postgraduate School in this investigation.
