In this paper, the calculation method of dynamic stress concentration around piezoelectric ceramics containing regular n-sided holes under action electroelastic coupling wave was studied, and it applied to promising barium calcium zirconate titanate material. First, governing equations were decomposed by using auxiliary function method, solution forms elastic field electric obtained expansion m...

Protonic conductors of BaZr0.5Ce0.3Ln0.2O3-δ (BZCLn532, Ln=Y, Sm, Gd, Dy) were successfully synthesized by using a cost-effective solid state reactive sintering (SSRS) method with 1 wt.% NiO as a sintering aid. The pellets of the BZCLn532 were obtained at sintering temperatures between 1300 1600 °C. The results show that the morphologies and the final relative densities of the obtained BZCLn532...

The use of piezoelectric ceramic transducers (such as Lead-Zirconate-Titanate-PZT) has become more and more widespread for Structural Health Monitoring (SHM) applications. Among all the techniques that are based on this smart sensing solution, guided waves and electro-mechanical impedance techniques have found wider acceptance, and so more studies and experimental works can be found containing ...
