High Cycle Fatigue Small Stressed Volume Design
High cycle fatigue (HCF) testing is used to analyze the behavior of metallic alloys in various aerospace applications. It is known that specimens with lower stressed volumes tend towards higher fatigue resistance. Aerospace components can have stressed volumes smaller (<10-6 in3) than traditional fatigue specimens. To capture the true fatigue capability of these components, small volume specimens are required. Another challenge with HCF is the time required to test specimens. To be capable of testing accurate stressed volumes in an efficient manner, the project scope is to design specimens and a fixture that can simultaneously test multiple specimens in a load frame. The team is tasked with demonstrating the ability to manufacture the specimens and fixture with simple manufacturing machinery and maintaining a uniform, uniaxial force distribution on each test specimen throughout the duration of testing.
