“…In particular the DIC technics allow the local analysis close to the interface area by means of the measurement of displacements directly above and below the interface. It may help to access the interface mechanical behavior and some of the above parameters [24] facilitating a more accurate analysis of debonding mechanisms and interface behavior.…”

The following recommendations are based on the chapter III of a State of the Art review conducted by the Task Group 2 of the RILEM Technical Committee 241-MCD ''Mechanisms of cracking and debonding in asphalt and composite pavements'' (Petit et al in Mechanisms of cracking and debonding in asphalt and composite pavements. Chapter III of the State-of-the-Art report of the RILEM technical committee 241-MCD series, vol 28. Springer, New York, pp 103-154. ISBN 978-3-319-76848-9 2018). The recommendations mostly concern "pure" fracture mode test methods that are currently used worldwide and even standardized, while mixed mode test methods developed by few research teams have not received full attention. This paper intends to give guidance for the application and characterization of interlayer bond testing, looking at the appropriate test methods and the importance of influencing parameters.

“…This technique has been deployed since 1980 in order to deepen knowledge about the determination of crack opening (Sutton et al, 1983;Roux et al, 2009;Hild and Roux, 2006;Pop et al, 2011, Buttlar et al, 2014. The principle of this technique is to follow the positional changes of a speckled pattern located on the sample surface.…”

“…Lagattu et al [7] sprayed a special mixture containing very fine white and black powders on the specimen surface. William et al [15] sprayed a layer of black paint on the specimen surface before spraying with white paint, however, the procedures of these spraying methods are complex, and the random distribution of speckle cannot be guaranteed.…”

Fatigue crack is one of the most common damage forms for aeronautical aluminum alloy. With crack propagation, the strain fields of the whole object surface and plastic zone (PZ) ahead of the crack tip are changing continuously. For most metallic materials, the behavior of PZ around the crack tip and continuous strain variation play a vital role in crack propagation. In this work, the “continuous” strain information at and in front of the crack tip on the specimen surface was obtained quantitatively and the PZ size ahead of crack tip was in situ measured quantitatively with crack propagation by using the digital image correlation (DIC) method, which overcomes the difficulty for the in situ measurement of mechanical variables. Moreover, the method of specimen preparation was simplified by using a white matt paint with strong adhesion, but also resulted in a higher resolution being shown, even for such a large area. Furthermore, the experimental results of the PZ size from the proposed method had good agreement with the theoretical values, which overcomes the limitation that the conventional approaches only consider the quasi-static crack. Finally, the continuous strain variation behavior was analyzed from the experimental results in detail with the consideration of crack propagation.
