The NDT of adhesive joints using ultrasonic spectroscopy
NDT & E International, 1989 The use of ultrasonic spectroscopy for the non-destructive determination of the cohesive properties of the adhesive layer in a joint is described. It has been shown that measurements of the through thickness natural frequencies of the joint obtained using ultrasonic spectroscopy can be used to calculate the modulus and thickness of the adhesive layer ...

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
