Two dimensional steady, laminar and incompressible motion of a micropolar fluid between an impermeable disk and a permeable disk is considered to investigate the influence of the Reynolds number and the micropolar structure on the flow characteristics. The main flow stream is superimposed by constant injection velocity at the porous disk. An extension of Von Karman’s similarity transformations ...

By using the numerical inverse Laplace transform based on modified Prudnikov formula, we construct solution of a nonstationary problem heat conduction for thermally sensitive half space operating in contact with layer under conditions convective exchange medium constant temperature. The thermoelastic state this piecewise homogeneous structure is investigated case where temperature kept surface.

This article is concerned with the theoretical analysis of the functionally graded magneto-electro-thermoelastic hollow sphere due to uniform surface heating. We analyze the transient thermoelastic problem for a functionally graded hollow sphere constructed of the spherical isotropic and linear magneto-electro-thermoelastic materials using a laminated composite mode as one of theoretical approx...

micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. an essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. efficiency and robustness of the implementation hinge on the type of inte...

Abstract The aim of the present paper is to study impact diffusion and impedance parameters on propagation plane waves in a thermoelastic medium for Green Lindsay theory (G-L) Coupled (C-T) thermoelasticity. Results are demonstrated boundary conditions amplitude ratios various reflected against angle incidence calculated numerically. characteristics diffusion, relaxation time impedence paramete...

This paper presents a nonlinear model of a clamped-clamped microbeam actuated by an electrostatic load with stretching and thermoelastic effects. The frequency of free vibration is calculated by discretization based on the Differential Quadrature (DQ) Method. The frequency is a complex value due to the thermoelastic effect that dissipates energy. By separating the real and imaginary parts of fr...

In this paper we extend the conditions on quasi-thermal-incompressible materials presented in [1] so that they satisfy all the principles of thermodynamics, including the stability condition associated with the concavity of the chemical potential. We analyze the approximations under which a quasi-thermal-incompressible medium can be considered as incompressible. We find that the pressure cannot...
