Free vibration of a magnetoelectroelastic plate resting on a Pasternak foundation is investigated based on Mindlin theory. The in-plane electric and magnetic fields can be ignored for plates. According to the Maxwell equation and magnetoelectric boundary condition, the variation of electric and magnetic potentials along the thickness direction of the plate is determined. Using Hamilton’s princi...

In this study, a semi analytical method for transverse and axial vibration of single-walled boron nitride nanotube (SWBNNT) under moving a nanoparticle is presented. The surrounding elastic medium as Pasternak foundation and surface stress effect are included in the formulations of the proposed model. Using Timoshenko beam theory (TBT), Hamilton’s principle and nonlocal piezoelasticity theory, ...

VISCO is a novel visual extension to the texbased SALIERI Language. VISCO makes it possible to use the SALIERI System for creating nearly any kind of score level or real-time music applications with integrated graphical user interfaces. The visual control elements and environments can be created and controlled with the integrated, interactive, GUI based VISCO Browser, from within running SALIER...

The instability of the plane interface separating the two uniforms, superposed, electrically conducting and counter streaming elastico-viscous fluids through a porous medium is examined for visco-elastic polymer solutions in the presence of a horizontal magnetic field and also in the presence and absence of surface tension. These solutions are known as Walters’ (model B  ) fluiare approximated...

Opioids are some of the most effective pain-relieving drugs used in the clinical management of pain (Gilman et al. 1990). In addition to their analgesic effect, opioid peptides and alkaloids also affect a number of physiological functions including hormone secretion, neurotransmitter release, feeding, gastrointestinal motility, and respiratory activity (Pasternak 1988). Extensive physiological,...

in this paper, asymmetric buckling analysis of functionally graded (fg) circular plates with temperature dependent property that subjected to the uniform radial compression and thermal loading is investigated. this plate is on an elastic medium that simulated by winkler and pasternak foundation. mechanical properties of the plate are assumed to vary nonlinearly by temperature change. the equili...

Crucial to an understanding of the mechanism of cell replication is a knowledge of the manner in which intracellular and surface membranes develop between successive divisions . The application of zonal centrifugation to separate cells according to their size and hence their relative age (Warmsley and Pasternak, 1970) has enabled us to study the timing of these events by measuring changes in fo...

Abstract Variational principles and variationally consistent boundary conditions are derived for a system of double Rayleigh beams undergoing vibrations subject to axial loads. The elastic layer connecting the modelled as three-parameter nonlinear Winkler–Pasternak with Winkler having linear components Pasternak only component. forced freely vibrating beam using semi-inverse approach. Hamilton’...
