Shear Piezoelectricity in Poly(vinylidenefluoride<i>co</i>trifluoroethylene): Full Piezotensor Coefficients by Molecular Modeling, Biaxial Transverse Response, and Use in Suspended EnergyHarvesting Nanostructures

چکیده
In addition, they do not need to be poled because they directly crystallize from melt or solution into the ferroelectric (β-) phase. Piezoelectricity in these materials is related to the electronegativity difference in hydrogen and fl uorine atoms, which determines an effective dipole moment in the direction normal to the carbon backbone. Consequently, these fi lms or nanostructures are often utilized with top/bottom contacts. [ 20–23 ]

متن کاملDynamic response determination of viscoelastic annular plates using FSDT – perturbation approach
In this paper, the transient response of a viscoelastic annular plate which has time-dependent properties is determined mathematically under dynamic transverse load. The axisymmetric conditions are considered in the problem. The viscoelastic properties obey the standard linear solid model in shear and the bulk behavior in elastic. The equations of motion are extracted using Hamilton’s principle...
