In order to solve the problems of limited installation space and strict additional quality, effects internal distributed nonlinear energy sinks (NES) considering optimal locations on a composite truss core sandwich plate are investigated in this paper. Choose five NESs here inset them different places suppress vibration plate, which is excited by half-wave shock. The coupled dynamic equations s...

staining. However, these visualization methods require either expensive or hazardous radioactive chemicals and Microsatellite DNA markers are widely used in genetic research. are time-consuming. Electrophoresis with MetaPhor Their use, however, can be costly and throughput is sometimes limited. The objective of this paper is to introduce a simple, low-cost, highagarose gels (Cambrex Corporation...

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...
