In this article thermoelastic damping in nano-beam resonators is investigated based on nonlocal theory of elasticity and the Euler-Bernoulli beam assumptions. The governing equation of deflection of the beam is obtained from shear and moment resultants and stress–strain relationship of the nonlocal elasticity model and also the governing equations of thermoelastic damping are established by usi...

In device applications of carbon nanotubes, characterization of the heat transfer is essential. While experimental attempts to characterize heat conduction of carbon nanotubes encounter technical difficulties, the classical molecular dynamics (MD) simulations hold an advantage as the heat conduction is phonon-dominated. Single-walled carbon nanotubes (SWNTs) are expected to possess high thermal...

background: the use of organophosphates (ops) in developing countries is rising in large quantities and non-secure methods. this problem not only causes acute poisoning but also may lead to chronic diseases such as polyneuropathy. in iran, 60% of pesticides are organophosphate compounds that may lead to delayed polyneuropathy. objectives: the purpose of the current study was to evaluate delayed...

We study the behavior in time of solutions to several systems equations for porous-thermo-elastic problems when one variables is considered be quasi-static or, other words, whose second derivative can neglected. analyze three different situations using classical Fourier law and also type II or III Green–Naghdi heat conduction models.
