Providing of Rod Piezoceramic Electroacoustic Transducers Thermal Mode Operation [PDF]

Microsystems, Electronics and Acoustics, 2019
The basis of the electro-acoustic transducer is piezoceramics - a quite fragile material. A rod type transducer was chosen for analysis due to the lack of research on this type of transducer and its widespread use. The most dangerous operational load is thermal.

Inferring cumulative crack widths in reinforced concrete structures using Coda Wave Interferometry of ultrasound

Structural Concrete, Volume 27, Issue 1, Page 247-262, February 2026.
Abstract Whether concrete structures are cracked, how wide these cracks are, and whether they must be regarded as damaging, is a central issue in structural health monitoring. Ultrasonic measurements evaluated with the sensitive Coda Wave Interferometry (CWI) have the potential to detect cracks early—long before they become visible. This paper presents

Low‐Temperature Co‐Firing and Synergistic Performance Optimisation of Ba(Zr0.2Ti0.8)O3 Ceramics Achieved by Doping With Trace Amounts of BaO–B2O3–SiO2 Glass

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
Solid‐state synthesised (Ba, Zr)TiO3 glass‐ceramics with 0–0.15 wt.% BaO–B2O3–SiO2 show reduced sintering temperature, > 96% density, and favourable dielectric properties for lead‐free low‐temperature co‐fired MLCCs. ABSTRACT Ferroelectric (Ba, Zr)TiO3 (BZT) glass‐ceramics doped with varying BaO–B2O3–SiO2 glass contents (0–0.15 wt.%) were synthesised ...

Method and apparatus for minimizing multiple degree of freedom vibration transmission between two regions of a structure [PDF]

, 1992
Arrays of actuators are affixed to structural elements to impede the transmission of vibrational energy. A single pair is used to provide control of bending and extensional waves and two pairs are used to control torsional motion.

State‐of‐the‐Art Review of Vibration‐Based Health Monitoring of Piles

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Vibration‐based health monitoring (VHM) has emerged as a promising technique for assessing the integrity of deep foundations by interpreting variations in dynamic response governed by soil–pile interaction. This review presents the theoretical background of foundation failure mechanisms, sensing technologies, and numerical approaches that underpin VHM ...
