Abstract In this paper, the solution to a coupled flow problem for micropolar medium undergoing structural changes is presented. The occur because of grinding in funnel-shaped crusher. standard macroscopic equations mass and linear momentum are solved combination with balance equation microinertia tensor containing production term. constitutive describe viscous material viscosity coefficient de...

The properties of Rayleigh-type surface wave in a linear, homogeneous and transversely isotropic nonlocal micropolar piezoelectric solid half-space are explored. Dispersion relations for derived both charge free electrically shorted cases. Using an algorithm iteration method MATLAB software, the speed Rayleigh is computed relevant material constants. effects nonlocality, angular frequency, micr...

Solid polycrystalline materials undergoing diffusion creep are usually described by Cauchy continuum models with a Newtonian viscous rheology dependent on the grain size. Such lacks rotational degrees of freedom needed to describe rotation. Here we provide more general description that includes rotation, and identifies deformation material micropolar (Cosserat) fluid. We derive expressions for ...

This investigation deals with the effect of variable thermal conductivity in a micropolar thermoelastic medium without energy dissipation cubic symmetry. The normal mode technique is employed for obtaining components physical quantities such as displacement, stress, temperature distribution and microrotation.

In this paper the two-dimensional flow of a micropolar fluid through porous medium over a continuously moving porous vertical plate under the combined buoyancy effects of thermal and heat source has been studied under the action of transverse magnetic field taking into account the thermal radiation field. The Roseland approximation is used to describe radiative heat transfer in the limit of opt...

The in-plane behaviour of tetrachiral lattices should be characterized by bi-dimensional orthotropic material owing to the existence of two orthogonal axes of rotational symmetry. Moreover, the constitutive model must also represent the chirality inherent in the lattices. To this end, a bi-dimensional orthotropic chiral micropolar model is developed based on the theory of irreducible orthogonal...
