Design and mechanical characterization of fibre optic plate sensor for cracking monitoring
TL;DR: In this paper, the authors describe the characteristics of fiber optic sensors for crack monitoring and a description of improvements, which can be used to detect and monitor flexural cracks in bridges, which are essentially perpendicular to the spanning direction.

- 18 Sep 2017
TL;DR: In this paper, the authors used the Digital Image Processing method to capture the opening of a single crack in a double edge-notched SHCC specimen under tension, and the test results are compared with a previous method based on the displacement over a gauge length and theoretical simulation based on micromechanics.
