STRAIN MONITORING APPARATUS AND METHODS FOR USE IN MECHANICAL STRUCTURES SUBJECTED TO STRESS |
摘要 |
Devices and methodology are provided for measuring mechanical strain in a structural member. The devices and methodology utilize a material which undergoes a change in phase when strained so that measurement of the phase change indicates strain. Preferably the phase change material is a transformation induced plasticity steel alloy. The elements may be configured as gauges secured to a structural member, but also the elements may perform as part of the structure. A plurality of elements may be organized into a monitoring system, either passive or active, for a complex structure.
