A continuum model of piezoelectric material with strain and electric gradient effects is proposed in this work. An energy variational principle strain, gradient, field as independent variables presented to develop the equilibrium equations all boundary conditions. Moreover, two internal length characteristics underlying microstructure are introduced constitutive equations. This employed an anti-plane problem material, a general solution obtained polar coordinates. Special attention paid...
Abstract A piezoelectric beam model with strain gradient and electric effects is proposed. An energy variational principle strain, gradient, field, field considered as independent variables postulated to develop the governing equations boundary conditions. Moreover, two coefficients one coefficient are introduced account for higher order coupling of underlying microstructure. Then bending problem a cantilever solved illustrate theory. It found that deflection may depend strongly on...
The work reported in this paper aims at studying the magneto-electric field variation accounting for a thin interphase layer with different materials. Thin within solid can significantly affect overall response of composite material. In order to obtain phenomenon, we replace by an imperfect interface appropriately devised conditions. To get conditions, Taylor expansion relevant physical fields region is introduced. Those conditions do not involve interphase, which just have relation material...
<title>Abstract</title> Oedaleus decorus asiaticus (O-decorus) is a significant pest in the grasslands of Inner Mongolia, posing considerable challenges to development animal husbandry. To understand key factors influencing population distribution O-decorus, field surveys were conducted from 2018 2020, during which count, growth stage, and location information O-decorus recorded. Daily soil moisture (SM) data daily land surface temperature (LST) obtained National Tibetan Plateau Data Center,...
Plasma instabilities are a major concern in plasma science, for applications ranging from particle accelerators to nuclear fusion reactors. In this work, we consider the possibility of controlling such by adding an external electric field Vlasov--Poisson equations. Our approach determining is based on conducting linear analysis resulting We show that it possible select fields completely suppress present system when equilibrium distribution and perturbation known. fact, proposed strategy...
Abstract Highly compliant structures such as microbeams can deform substantially in response to interactions between molecules adsorbed on their surface. To understand systems and improve detection signals, a mechano-electro-chemical coupling model for mechanical deformations of the immobilized single-stranded DNA (ssDNA) is established due flexoelectricity. The governing equations corresponding boundary conditions ssDNA are derived by using variational principle. bending (one cantilever...
