An eddy current testing method for detection of subsurface defects in reformer tubes

Lian Xie, Prashanth Baskaran, Bo Feng, Artur L. Ribeiro et autres

Subsurface defect detection in stainless-steel tubes is challenging due to low electrical conductivity, closed cross-sectional geometry, surface curvature and in-service inspection constraints. A probe-assisted signal processing method is proposed for high-sensitivity defect detection in reformer tubes under non-saturated conditions using eddy current …

An adaptive perception-based identification method for disturbed EMAT defect echoes

Fuchun Zhang, Jun Tu, Grzegorz Tytko, Zhiyang Deng et autres

Defect echoes acquired by electromagnetic acoustic transducers (EMATs) are often affected by time-delay drift, local waveform deformation, noise interference, and limited labelled data, making defect-type identification difficult. To address these issues, this paper proposes an adaptive perception-based identification method and develops an …

A Nonlinear Iterative Inverse Finite Element Approach for Shape Sensing of Beam Structure

Bingqian Zhou, Feifei Zhao, Zexing Yu, Bo Feng et autres

Shape sensing, which can real-time monitor the dynamics deformation of the engineering structure using the discrete surface strains, has a significance for structural health monitoring system (SHM). Nevertheless, the current shape sensing approaches is limited for monitoring the three-dimensional nonlinear displacements and …

Large Bandwidth and High Sensitivity Ultrasonic Transducers Based on High Temperature 1-3 Piezoelectric Composite Materials

Rui Zhang, Bo Ma, Yihua Kang, Shiyuan Liu et autres

High-temperature Pb(Zr,Ti)O₃ (PZT)/epoxy 1-3 composites were fabricated using the dice-and-fill technique. These composites exhibited dielectric permittivity (890), piezoelectric coefficient (450 pC/N), and electromechanical coupling coefficient kt (62%) at room temperature. To enhance thermal reliability at elevated temperatures, the epoxy filler was incorporated …

Backing Design for Coil-only EMAT using Nickel-powder Epoxy Composite

Yini Song, Kai WANG, Yiru Xiao, Jun Tu et autres

Coil-only magnetostrictive Lamb-wave detection employs a nickel sheet both as the waveguide and as an integral part of the ultrasonic excitation structure, but this configuration often produces multiple echo pulses that obscure interpretation. To mitigate unwanted reflections, we coated the nickel substrate …
