Recently, there has been high interest in the capabilities of non-linear ultrasound techniques for damage/defect detection as these techniques have been shown to be more sensitive than linear ultrasound techniques for certain types of damage. This pa

Autor: Andriejus Demcenko, Jonathan M. Cooper, Arno Volker, Michael Mazilu, Rab Wilson

JMC acknowledges EPSRC Fellowship (EP/K027611/1) and the ERC advanced investigator award (340117 - Biophononics). In this paper we show that acoustoelasticity in hyperelastic materials can be understood using the framework of non-linear wave mixing,

Self-healing composites using a thermally mendable polymer, based on Diels–Alder reaction were fabricated and subjected to various multiple damage loads. Unlike traditional destructive methods, this work presents a nonlinear ultrasound technique to

In this paper results from a non-linear AS (angular spectrum) based ultrasound simulation program are compared to water-tank measurements. A circular concave transducer with a diameter of 1 inch (25.4 mm) is used as the emitting source. The measured
