摘要：

Fiber-optic grating sensing based on Loop thin-walled ring section beam is proposed and demonstrated. The temperature and stress can be measured simultaneously using only one fiber grating. The strain of the thin-walled ring section beam is investigated theoretically and experimentally. The result shows the local strain varies as the cosine function of twice the positional angle.
