free vibration of sandwich plates with temperature dependent functionally graded (fg) face sheets in various thermal environments is investigated. the material properties of fg face sheets are assumed to be temperature-dependent and vary continuously through the thickness according to a power-law distribution in terms of the volume fractions of the constituents. also, the material properties of...

Peridynamics is a continuum theory that operates with non-local deformation measures as well long-range internal force/moment interactions. The resulting equations are of the integral type, in contrast to classical theory, which deals differential equations. aim this paper analyze peridynamic governing for elastic beams. To end, strain energy density formulated function curvature. By applying L...

In this paper, the buckling and vibration behaviour of functionally graded flexoelectric nanobeam is examined. The vibration and buckling formulations of functionally graded nanobeam are developed by using a new theory that’s presented exclusively for flexoelecteric nano-materials. So by considering Von-Karman strain and forming enthalpy equation based on displacement, polarization and electric...

The present study investigates the axial vibration of double-walled nanotubes. Using nanorod continuum model with van der Waals effect, vibrational frequencies are studied. Aydogdu (Journal Vibration and Control, Vol. 21, Issue 16, (2015), 3132-3154) proposed a reliable for in nanotube. This provided detailed investigation using effects. But sometimes, wrong equation might lead to erroneous sci...

In this paper, buckling and free vibration analysis of a circular tapered nanoplate subjected to in-plane forces were studied. The linear variation of the plate thickness was considered in radial direction. Nonlocal elasticity theory was employed to capture size-dependent effects. The Raleigh-Ritz method and differential transform method were utilized to obtain the frequency equations for simpl...

In this paper, axisymmetric free vibration analysis of a circular Nano-plate having variable thickness was studied. The variation in thickness of plate was considered as a linearly in radial direction. Nonlocal elasticity theory was utilized to take into account size-dependent effects. Ritz functions was utilized to obtain the frequency equations for simply supported and clamped boundary. To ve...

Monique DAUGE and Isabelle GRUAIS Abstract. This paper deals with the asymptotics of the displacement of a thin elastic plate when it is submitted to various boundary conditions on its lateral face: namely, hard and soft clamped conditions, and hard support. Of particular interest is the in uence of the edges of the plate where boundary conditions of di erent types meet. The singular perturbati...

In this study, the effect of design parameters such as pipe diameter, wall thickness, material and fluid velocity on natural frequency fluid-structure interaction in straight conveying fully developed turbulent flow were investigate numerically,analytically experimentally. Also support conditions, simply-simply clamped-clamped was investigated. Experimentally, vibrations characterized by accele...

The consistency of the constraint with the evolution equations for spatially inhomogeneous and irrotational silent (SIIS) models of Petrov type I, demands that the former are preserved along the timelike congruence represented by the velocity of the dust fluid, leading to new non-trivial constraints. This fact has been used to conjecture that the resulting models correspond to the spatially hom...

The Na(+)-bile acid cotransporters NTCP and ASBT are largely responsible for the Na(+)-dependent bile acid uptake in hepatocytes and intestinal epithelial cells, respectively. This review discusses the experimental methods available for demonstrating electrogenicity and examines the accumulating evidence that coupled transport by each of these bile acid transporters is electrogenic. The evidenc...
