Abstract The susceptibility of mechanomyography (MMG) signals acquisition to sensor donning and doffing, and the apparent time-varying characteristics of biomedical signals collected over different periods, inevitably lead to a reduction in model rec

This study investigates viscoelastic guided wave properties (e.g., complex–wavenumber–, phase–velocity–, and attenuation–frequency relations) for multiple modes, including different orders of antisymmetric, symmetric, and shear horizontal m

Pattern recognition of lower-limb movements based on mechanomyography (MMG) signals has a certain application value in the study of wearable rehabilitation-training devices. In this paper, MMG feature selection methods based on a chameleon swarm algo

Nonlinear guided elastic waves have attracted extensive attention owing to their high sensitivity to microstructural changes. However, based on the widely used second harmonics, third harmonics and static components, it is still difficult to locate t

The nonlinear interaction of the guided waves has attracted considerable attention since it shows high sensitivity to the material damage at the early stage and can isolate nonlinearity caused by the measurement system. A suitable mode triplet is sel

Scanning non-collinear wave mixing for nonlinear ultrasonic detection and localization of plasticity
Publikováno v:
NDT & E International. 93:1-6
Non-collinear wave mixing recently has been proposed to detect and localize micro-damage in materials. It is proved sensitive to the interaction angle α of the incident waves. In this work, the relationship between the acoustic nonlinearity paramete

Experimental and numerical investigations of nonlinear interaction of counter-propagating Lamb waves
Publikováno v:
Applied Physics Letters. 114:011902
The nonlinear interaction of Lamb waves has attracted considerable attention because of its potential for localizing micro-damage in plate-like structures. Most recent studies have focused on the nonlinear mixing of Lamb waves propagating in the same
