... Defect-Selective Imaging by Nonlinear Air-Coupled Ultrasound . ... Improved non-destructive testing techniques are required for new kinds of materials. ... In this study, this technique has been applied to non-destructive imaging in which a transducer attached to the sample (or embedded into it, e.g. in shape-adaptive structures) injects ultrasound into the sample to be inspected, while a focused narrowband air-coupled ultrasound receiver scans across the sample to monitor the local vibration. ...

... Development of a Nonlinear Boundary Condition Approach as a New Model for the Nonlinear Acoustic Interface Problem . ... A new theoretical approach to dealing with acoustic interface nonlinearities is presented. This approach allows one to write down a set of nonlinear boundary conditions for the interface, which then allows solutions to be developed within the conventional framework of continuum mechanics. ...

... Diagnostics of the Medium Structure by Long Nonlinear Wave . ... The important result of this model is that the structure of a medium always increases the nonlinear effects under the propagation of long waves, and that non-linearity takes place even for media with the components described by the linear law. This effect forms the basis of a new method for diagnostics of the properties of medium components by long non-linear waves. ...
... Differential Invariants for a Class of Nonlinear Wave Equations . ... We consider a class of wave equations studied some ten years and by applying an infinitesimal technique recently developed by one of the A.A.
