Microstructured Optical Fiber Bragg Grating-Based Shear Stress Sensing In Adhesive Bonds
23RD INTERNATIONAL CONFERENCE ON OPTICAL FIBRE SENSORS(2014)
摘要
We present shear stress sensing with a Bragg grating sensor fabricated in a highly birefringent microstructured optical fiber. This sensor has a shear strain sensing resolution of 0.04 pm/mu epsilon when embedded in a shear loaded adhesive bond. We achieve discrete shear stress mapping in an adhesive bond by embedding a multitude of these sensors at different locations in the bond line. Experiments and numerical modeling show the limited influence of angular misalignment of the sensor on its shear stress response. Finally, we discuss the cross-sensitivity of this sensor to shear strain and temperature.
