TL;DR: A finite element model was developed for vibration analysis of sandwich beam with a viscoelastic material core sandwiched between two elastic layers and the results showed that the finite model presented here had good accuracy and efficiency in the specific frequency range of interest.

TL;DR: In this paper, an air-coupled ultrasonic method, focusing on the problem that weak bonding interface is difficult to accurately measure using conventional nondestructive testing technique, is proposed to evaluate the bond integrity.

TL;DR: Based on the spring model and the potential function theory, a theoretical model is developed by the transfer matrix method to predict the transmission spectrum in a double-layered bonded structure and it is observed that the resonant transmission peaks move towards a higher frequency with the increase of the normal interfacial stiffness.

TL;DR: Athree-layer composite plate element is developed for finite element modeling and vibration analysis of sandwich plate with frequency-dependent viscoelastic material core and has certain reference and application value for solving similar engineering vibration problems.

TL;DR: In this article, an ultrasound delay time spectrum method was proposed to evaluate the interfacial stiffness coefficient of rubber thin layers with different interfaces, and the results showed that the delay time peak of the weak bonding interface is much greater than that of the perfect interface, and that the period of resonant frequency has a great positive correlation with the thickness of the thin layer.
