In this paper, mixed convection flow of couple stress fluid in circular annulus is studied. First order chemical reaction, Soret and Dufour effects are taken into consideration. The governing partial differential equations are transformed into a system of ordinary differential equations and solved by Homotopy Analysis Method (HAM). The effects of Soret number, Dufour number, chemical reaction p...

An investigation has been made to study the off-centered stagnation flow of a couple stress fluid over a rotating disk. The model developed for the governing problem in the form of partial differential equations has been converted to ordinary differential equations with the use of suitable similarity transformation. The analytical approximation has been made with the most promising analytical a...

In the present study, a vibration analysis of functionally graded rectangular nano-/microplates was considered based on modified nonlinear coupled stress exponential and trigonometric shear deformation plate theories. Modified coupled stress theory is a non-classical continuum mechanics theory. In this theory, a material-length scale parameter is applied to account for the effect of nanostructu...

Leadership under stress appears to be a constantly central issue in applied psychology. In his latest review (1990), B. M. Bass lists approximately 200 articles, books, and chapters in books in the chapter titled “Stress and Leadership.”1 However, leadership under severe stress appears to have attracted less attention. In a recent (January 2000) survey of the literature (PsyLit, from 1887), lea...

A nonlinear couple modeling of magnetostrictive cantilever is built by combining Gibb’s free energy formulation with the Euler-Bernoulli beam theory. The Gibb’s free energy corresponding to different orientations in 3D space can be expressed in terms of their direction cosines, the stress at a given point can be described by classical theory. The magnetomechanical bending experimental setup is ...
