It is advantageous in the field of structural monitoring for fatigue fuses that are engineered to break in sequence to both be mounted near each other and also to work toward ensuring the fatigue fuses all undergo similar load cycling.

These components work together to ensure that each fatigue fuse in a set undergoes more uniform load cycling, thereby improving structural monitoring performance.
