Ultrasonic detection of delamination in stringer-stiffened panels made carbon fiber-reinforced plastics (CFRPs) presents a critical challenge due to their complex geometry, complicated properties and large size. In this work, method using the wavefield curvature A0-mode Lamb wave is proposed. Firstly, underlying mechanism numerically investigated examine interactions between at different sites stringer. Then, sensitive local anomalies revealed owing higher-order derivative nature....

Abstract The co‐generation of electricity and chemicals via direct internal reforming solid oxide fuel cells (DIR‐SOFCs) offers a promising route to carbon‐neutral energy solutions. However, challenges such as inadequate performance fast degradation, particularly when using hydrocarbon fuels like CH 4 , hinder the deployment DIR‐SOFC technology. This study addresses three critical issues: effect composition on electrochemical properties, mechanisms microstructural impacts carbon deposition,...

This paper describes the first application of a remote nondestructive laser ultrasonic (LU) system for clinical diagnosis cracks in human teeth, to our knowledge. It performs non-contact detection on small-dimension teeth samples. Two extracted with different types (cracked tooth and craze lines), which have crack depths, are used as experimental A series waves were generated by scanning laser-line source technique detected laser-Doppler vibrometer two The B-scan images peak-to-peak...
