The present work investigates the elasto-visco-plastic buckling of thick plate structures. Methods to estimate thin shells and plates are proposed in literature. To knowledge authors, only few works experimental results, none treat plate. Thick rectangular chosen as a structure interest study buckling. A modelling/experimental approach is followed solve such problem. Buckling experiments at roo...

An apparatus for continuous registration of the electric field within an electrophoretic column was developed. It comprises a rectangular separation trough with an ordered array of 256 electrodes over a length of 10 em and perpendicular to the current flow. Electrodes are photoetched on a supporting glass plate from a vapor deposited thin layer of Sno 2 semiconductor (width: 6011m, height: O.ll...

in this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (er) fluid core is investigated. the rectangular plate is covered an er fluid core and a constraining layer to improve the stability of the system. the two outer layers of the sandwich structure are elastic. the viscoelastic materials express the middle layer behavior under electric field and small st...

The periodic flexural-gravity waves propagating along a frozen channel are investigated. has rectangular cross section. fluid in the is inviscid, incompressible and covered with ice. ice modeled by thin elastic plate whose thickness varies linearly. Two cases have been considered: symmetrically across channel, being smallest at center of largest walls; from value one wall to another wall. 2D pr...

The present paper treats the problem of finding the asymptotic bounds for the globally optimal locations of orthogonal stiffeners minimizing the compliance of a rectangular plate in elastostatic bending. The essence of the paper is the utilization of a method of analysis of orthogonally stiffened rectangular plates first presented by Mazurkiewicz in 1962, and obtained herein in a closed form fo...

This study presents critical buckling of functionally graded soft ferromagnetic porous (FGFP) rectangular plates, under magnetic field with simply supported boundary condition. Equilibrium and stability equations of a porous rectangular plate in transverse magnetic field are derived. The geometrical nonlinearities are considered in the Love-Kirchhoff hypothesis sense. The formulations are compa...

In this article, we have considered a nonlinear nonlocal time dependent fourth order equation demonstrating the deformation of thin and narrow rectangular plate. We propose $$C^1$$ conforming virtual element method (VEM) arbitrary order, $$k\ge 2$$ , to approximate model problem numerically. employ VEM discretize space variable fully implicit scheme for temporal variable. Well-posedness discret...

In this paper, a comprehensive study on the performance of parallel plate and rectangular micro channel counter flow heat exchangers is presented. The geometrical parameters of the two configurations are optimized for a given heat transfer rate, effectiveness and pressure drop. In case of rectangular micro channel counter flow heat exchanger, a reduced order model is developed first in which re...

In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...
