A review of non-destructive techniques used for mechanical damage assessment in polymer composites (2018, methodology): “have used a vibro-acoustic wave modulations technique, which is based on the combination of two excitation frequencies: a high frequency of a few tens of kHz and a low resonance frequency [72].”
Damage identification in aircraft composite structures: A case study using various non-destructive testing techniques (2015, background): “Aymerich and Staszewski [11] proposed a technique based on nonlinear acoustic measurements, which allows for detection of damage in a tested structure.”
Impact damage identification in composite laminates using vibration testing (2014, methodology): “Because the delamination mode can introduce non-linearities Aymerich and Staszewski [22], an effort was made to minimise them by using mini hammer transducer to create a low-level input excitation.”
