As the application of composite materials in structural parts continues to increase, so does
the importance to monitor the structure's health condition during their entire service life. This …

The usual way to evaluate the fracture toughness of bonded joints is via experimental
characterization of the critical strain energy release rate. Different test procedures and data …

Due to the extreme temperature with significant variation in the alpine region, the tunnels in
this area are subjected to intense freeze–thaw cycles and frost heaves, which leads to the …

Conclusion A method to monitor the coal mine roadway roof separation by FBG
displacement sensors is reported. This method has been applied in Zhu Xian-zhuang coal …

Fatigue crack growth in composite, single lap bonded joints is analysed by back face
distributed strain sensing, using optical backscatter reflectometry. Crack growth is inferred …

We propose a peak seeking algorithm to extract the damage characteristic-variation of
central wavelength to monitor the crack damage status in aluminum alloy plates using …

A fatigue fracture mechanics method was developed, implemented and used to characterize
the crack kinetics of laminated electrical steel. Tests were carried out on double cantilever …

In this paper, the back-face technique is exploited to monitor fatigue crack growth (FCG) in a
composite, single lap adhesive bonded joint, using distributed sensing by Optical …

This paper details a study which was carried out on the application of FBG sensors for
investigation of delamination crack status in glass fibre reinforced composite materials. A …

In this study, the backface strain (BFS) is measured by both digital image correlation (DIC)
and fiber optic sensors (FOS) to detect the crack initiation and propagation in adhesively …
