Investigation of generalized piezoelectric-thermoelastic problem with nonlocal effect and temperature-dependent properties

Abstract

In the generalized thermoelasticity with fractional order heat conduction and nonlocal elasticity, a generalized piezoelectric-thermoelastic problem of a both-end-fixed finite length piezoelectric rod with temperature-dependent properties and subjected to a moving heat source is investigated. The dimensionless governing equations are formulated and then solved by Laplace transform and its numerical inversion. In calculation, the effects of the nonlocal parameter, the fractional order parameter and the temperature-dependent properties on the non-dimensional temperature, displacement, stress and electrical potential are explored and demonstrated graphically. The results show that they significantly influence the peak value or magnitude of the considered physical variables.

Study of micro‐elongated thermoelastic medium loaded with a piezoelectric layer under the influence of gravity using the dual‐phase‐lag model

“…Following this, Lee et al 5 published a research paper in which they investigated virus‐based piezoelectric energy generation. Recently, Li and He 6 published their findings on a general linear piezoelectric–thermoelastic problem for nonlocal effects and temperature‐reliant characteristics.…”

A review of size-dependent continuum mechanics models for micro- and nano-structures

“…Various mechanical behavior can be addressed under different external loadings, which can affect noticeably stiffness, stress, strain, and deformation of the micro/nano-structures. Therefore, the importance of investigating the effects of Fourier/non-Fourier heat conduction, coupled thermoelasticity analysis including the classical coupled and Lord-Shulman coupled models, uncoupled magneto-thermoelasticity analysis, as well as electro-thermoelasticity behavior is essential on the mechanical behavior of micro/nano sized-structures [210][211][212][213][214][215][216][217][218][219][220][221][222][223][224][225][226][227][228][229].…”

Reflection/transmission of plane waves at the interface of an ideal fluid and nonlocal piezothermoelastic medium

“…Kumar and Sharma (2017) discussed the reflection of plane waves at the interface of elastic/piezothermoelastic solid half-spaces with fractional-order derivatives. The nonlocal generalized elasticity theory for piezothermoelastic materials with thermal characteristics was established by Li and He (2018). In the context of MDD and two-temperature theories, Sur and Mondal (2020) developed a nonlocal mathematical model.…”
