This communication reconsiders and reorganises parts of existing knowledge that refers to Cosserat-type hyperelasticity formulations in a manner respects pays tribute the early development pattern couple-stress theory and, also, associates with it more recent findings relevant discoveries related certain type polar hyperelastic behaviour fibrous composites. It further shows these different bran...

Abstract Based on the couple-stress theory, elastohydrodynamic lubrication (EHL) contact is analyzed with a consideration of size effect. The lubricant between surface homogeneous coated half-plane and rigid punch supposed to be non-Newtonian fluid. density viscosity are dependent fluid pressure. Distributions film thickness, in-plane stress, pressure calculated by solving nonlinear fluid-solid...

Rigidizable-Inflatable (RI) materials offer the possibility of deployable large space structures (C.H.M. Jenkins (ed.), Gossamer Spacecraft: Membrane and Inflatable Structures Technology for Space Applications, Progress in Aeronautics and Astronautics, 191, AIAA Pubs., 2001) and so are of interest in applications where large optical or RF apertures are needed. In particular, in recent years the...

This paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. The Cogley- Vincenti-Gilles equilibrium model is employed to include the effects of thermal radiation in the study. The governing boundary layer equations are transformed into a system o...

The integrated stress response (ISR) protects cells from numerous forms of stress and is involved in the growth of solid tumours; however, it is unclear how the ISR acts on cellular proliferation. We have developed a model of ISR signalling with which to study its effects on tissue growth. Overexpression of the ISR kinase PERK resulted in a striking atrophic eye phenotype in Drosophila melanoga...

Thermoelastic expansion due to frictional heating causes significant changes in contact pressure and temperature in energy dissipation systems uch as brakes and clutches. Finite element analysis of such systems tends to be extremely computer-intensive. We here present an alternative mplementation of the transient problem, based on the expression of the temperature and stress fields as modal exp...

We consider the system of equations determining linear thermoelastic deformations dielectrics within recently called Moore-Gibson-Thompson (MGT) theory. First, we obtain for such a case. Second, case rigid solid and show existence exponential decay solutions. Third, stability Exponential solutions in one-dimensional is also recalled.

It has been recently demonstrated [M. P. Blodgett and P. B. Nagy, J. Nondestruct. Eval. 23, 107 (2004)] that eddy current conductivity measurements can be exploited for near-surface residual stress assessment in surface-treated nickel-base superalloy components. To quantitatively assess the prevailing residual stress from eddy current conductivity measurements, the piezoresistivity coefficients...

Because of the wide variety of composite materials that are available, and the expense involved in testing to measure properties for design purposes (such as their damage tolerance), there is a need to develop predictive methods that can readily be utilised on desk-top computers. It is inevitable that such methods will be based on analytical rather than finite element techniques. A review is gi...

In this paper, the flow of couple stress fluid is investigated in a helical screw rheometer (HSR). By unwrapping the channel, lands, and the outside rotating barrel, the geometry of HSR is approximated as a shallow infinite channel. Both oneand two-dimensional analysis of the problem is presented using rectangular coordinates. In either case an exact solution of the flow problem is presented an...
