... distribution, and resulting fatigue strength, extensive experimental work as well as accompanying fracture analyses have been performed. Four-point rotating bending tests and alternating torsional tests were performed on a Ti-6Al-4V titanium alloy. Both smooth and notched specimen geometries were investigated...

...O Jin; JR Calcaterra; S Mall The present study was aimed towards improving the prediction capability of fretting fatigue life of Ti-6Al-4V. Incremental and interrupted fretting fatigue tests were conducted. Based on the crack propagation pattern observed on the fractured surface fretting fatigue...

... cycle fatigue behavior of Ti-6Al-4V. Endurance limit results were compared to similar data generated on conventional servohydraulic test systems and electromagnetic shaker systems to determine if there are any frequency effects. In addition, specimens were tested with and without cooling air...

...PJ Golden; T Nicholas The objective of this research was to measure the load history effects of negative stress ratio loading on the high cycle fatigue (HCF) crack growth threshold of Ti-6Al-4V. Previous work has shown an increase in the HCF threshold that is dependent on the K max during the low...
