Distributed Fiber-Optic System for Measuring Stress-Strain States of a Plate

Y. N. Kul'chin, B. S. Notkin
Keywords: distributed fiber-optic measuring system, structural inspection, strain measurements
Pages: 61-68


A distributed measuring system of the stress-strain state of a plate is developed and tested. Optical fiber is used as the recording element. It is fixed on the surface of the body being deformed so as to solve the problem with the minimum number of measurements. Theoretical calculations are confirmed by the results of full-scale experiments.
