Abstract In this paper, a kind of magnetorheological elastomer sandwich plate is proposed. The novel nonlinear differential term applied to describe the force-displacement curve elastomer. constitutive model system established using Hamilton Modeling Principle. By Galerkin dispersion, response equation obtained, and its stochastic dynamic behavior discussed. numerical results are simulated by M...

This paper aims to explore the working mechanism of sandwich-like meta-plates by periodically attaching nonlinear mass-beam-spring resonators for low-frequency wave attenuation. The MBS resonator consists a mass, cantilever beam, and spring provide negative stiffness in transverse vibration resonator; this is tunable changing parameters spring. Considering resonator, energy method applied obtai...

In the present article, buckling analysis of functionally graded annular thin and moderately thick plates under mechanical and thermal loads is investigated. The equilibrium and stability equations of the plate are obtained based on both classical and first order shear deformation plate theories. By using an analytical method, the coupled stability equations are converted to independent equatio...

Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...

Abstract: In this paper asymptotic models describing the mechanical and electric equilibrium state of two types of smart structures are presented and justified. The first structure consists of an anisotropic elastic thin plate with two surface bonded anisotropic piezoelectric patches and the second one is an anisotropic elastic sandwich thin plate with an inserted anisotropic piezoelectric patc...

Human pancreatic isolipases were separated by electrophoresis on cellulose acetate membrane. Band visualization by fluorescence detection of NADH produced by beta-oxidation cyclic reaction of fatty acid liberated from 1,2-dilinoleoylglycerol by lipase was achieved by making a two-plate "sandwich" of an electrophoresis plate and a substrate-bearing plate. Two true lipase forms, named L1 and L2 t...
