Coriolis effect on thermal convection in a couple-stress fluid-saturated rotating rigid porous layer [PDF]

open access: yes, 2011
Both linear and weakly nonlinear stability analyses are performed to study thermal convection in a rotating couple-stress fluid-saturated rigid porous layer. In the case of linear stability analysis, conditions for the occurrence of possible bifurcations

A 2D Inspired 4D Theory of Gravity [PDF]

open access: yes, 1994
Coadjoint orbits of the Virasoro and Kac-Moody algebras provide geometric actions for matter coupled to gravity and gauge fields in two dimensions. However, the Gauss' law constraints that arise from these actions are not necessarily endemic to two ...

Effect of the centrifugal force on the electromechanical instability of U-shaped and double-sided sensors made of cylindrical nanowires [PDF]

open access: yes, 2016
The U-shaped and double-sided nanostructures are promising for developing miniature angular speed sensors. While the electromechanical instability of conventional beam-type nanostructures has been extensively addressed in the literature, few researchers ...

Small size and rotary inertia effects on the natural frequencies of carbon nanotubes

open access: yesCurved and Layered Structures, 2018
In the present paper, rotary inertia and small size effects on the free vibration response of single-walled carbon nanotubes are examined. The equations in motion and associated boundary conditions are obtained by using Hamilton’s principle on the basis ...

Size-dependent behaviour of functionally graded microbeams using various shear deformation theories based on the modified couple stress theory [PDF]

open access: yes, 2016
This study investigates the mechanical behaviours of functionally graded (FG) microbeams based on the modified couple stress theory. The material properties of these beams are varied through beam’s depth and calculated by using classical rule of mixture ...
