Device for monitoring the fatigue life of a structural member and a method of making same

摘要

A device for monitoring the fatigue life of a structural member composed of a predetermined material, and a method of making same. The device is a substantially flat fuse composed of a material similar to the predetermined material and mountable on a structural member during use. The fuse has cut out portions which define fuse elements which also have reduced thicknesses to effect failure at different times in sequence because of fatigue and prior to the failure of the monitored structural member when the fuse and the monitored structural member are subjected to substantially the same stress history.
