Results are given for a finite crack in an infinite isotropic dielectric and for steady state cracking in a piezoelectric strip. In the latter problem, the effect of charge separation in the material and discharge in the crack are considered. Observations of crack behavior in piezoelectrics under ...
Moreover, it exhibits better photocatalytic activity (photodegradation of methylene blue organic dye) under visible light irradiation than pure ZnO powders (see Fig. 4.9). Sign in to download full-size image 4.8. Dielectric relaxation (a) and hysteresis loop (b) for the PMN-PT ceramics sintered...
Dielectric elastomers (DEs) respond to applied electric voltage with a surprisingly large deformation, showing a promising capability to generate actuation in mimicking natural muscles. A theoretical foundation of the mechanics of DEs is of crucial importance in designing DE-based structures and devices....

Generally, the dielectric, piezoelectric, elastic, and mechanical behavior of ferroelectric ceramics depend in a complex way on microstructural parameters such as porosity, grain size, and grain boundary effects. The properties of ferroelectric ceramics are also very sensitive to temperature, to stress ...
The maximum Vg that can be applied without dielectric breakdown is ∼2,000 V, which allowed us to reach maximum pressures around 30 kPa; the uncertainty in P is below 5% for all voltages. The deflection of the graphene membranes under applied pressure was determined via interferometric ...
The dielectric constant of the membranes is determined to maintain the Debye screening length equal to 10−7 m. This value, which is larger than the actual λ in Nafion™ membranes, is utilized to model high surface electrodes that significantly increase the capacity of the electric double...
The initial stresses widely exist in elastic materials. While achieving a continuum stress-free configuration through compatible unloading is desirable, me
