Abstract
A passive deflection gauge to detect peak deflection in a structural material or system since a given time is disclosed. The gauge includes any type of mechanical deflection sensor using a moveable or extensible core for measuring deflection. A stop moves the core only if a strain greater than the previously occurring maximum strain is present in the structural material or system. Any other movement of the stop will not move the core. Furthermore, a friction member may be incorporated to prevent spurious movement of the core.
