In this paper, a method to calculate the dynamic stress concentration around triangular defect of piezoelectric material under electroelastic coupling is studied and applied promising barium calcium zirconate titanate. Firstly, governing equation decomposed by decoupling technique, analytical solutions elastic wave field electric are obtained function expansion method. Then, conformal transform...

The effects of poly (vinylidene fluoride, PVDF) on barium zirconate titanate nanoparticles has been studied. Different concentrations (BZT-PVDF) nanocomposites using the formula [x (PVDF)/(1 − x) BZT] (where x = zero, 0.2, 0.4, 0.6, 0.8 and 1) were prepared hot pressing method. BZT nanoparticle was tartrate precursor route Dc resistivity as a function reciprocal temperature (1000/T) K−1 for com...

Yttria doped barium zirconate (BZY) is of interest for use as a catalyst support material, supporting exsolved Ni nanoparticles. Exsolution has been hypothesized to impart catalytic nanoparticles with exceptional resistance particle coarsening, known degradation mechanism in catalysts. However, the mechanisms and kinetics nanoparticle coarsening BZY are unknown. This work analyzes on epitaxial ...
