Abstract

A new type of fixture has been designed for low cycle fatigue testing. The fixture provides good alignment and reduces the setup time to a minimum. It is especially useful for testing at elevated temperatures. If specimens with uniform cross section in the gage length are used, then the need for a diametral strain gage is eliminated. The fixture is presently being used to measure low cycle fatigue crack growth in 316 stainless steel at elevated temperatures.
