“…In the past decades, although preliminary investigations on organic MCL-based detection methods have been carried out, there are still many challenges for applications in real engineering industry. [35,40] The metals and composites are widely used as structural materials of the equipment. The local strain concentration of the equipment in service is limited.…”

“…Therefore, TPE-4N provides new opportunities for developing large-scale and visual detection methods for structural damage. Qiu et al [34,35] detected the stree-strain distribution and fatigue crack propagation using the fluorescence response of TPE-4N films. The real-time fatigue crack length and fatigue crack growth rate can be obtained by fluorescence distribution.…”

“…Thus, the heterogenous strain distribution in the welded joint under monotonic tensile loading and cyclic loading can be evaluated from the fluorescence intensity 40 . Moreover, the fatigue crack length and growth path in aluminum alloy under biaxial loading are detected by fluorescence signal 41 . Besides metals, damage of composites is also successfully detected by TPE‐4N film.…”

“…40 Moreover, the fatigue crack length and growth path in aluminum alloy under biaxial loading are detected by fluorescence signal. 41 Besides metals, damage of composites is also successfully detected by TPE-4N film. Meng et al 42 proposed a direct visualization method based on TPE-4N film for detecting the interface debonding of fiberreinforced polymers.…”
