Abstract
A method for measuring fatigue on a metal or metal alloy structural part, which includes mounting a fatigue gage on a surface of the part, the fatigue gage being the same material as the part, applying electrical power on the gage and measuring the resistance of the fatigue gage, inspecting the fatigue gage at various time intervals by applying electric power on the gage and measuring the resistance of the fatigue gage; and analyzing the change of resistance of the fatigue gage at the various time intervals to determine fatigue on the part.
Claims6
