A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s composite beam functio...

In this study, the impact behavior of patch-repaired layered composite plates under low velocity loads was numerically investigated. For purpose, with holes different geometries in middle were repaired patches using various adhesives. Impact material investigated by dropping strikers speeds on plate. Layered plate used as sheet and patch material, orientation angles are [0 ° / 45 0 °] for patch...

This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...

ABSTRACT In this study, the vibration and sound radiation from the double-layered strip plate with air cavity between the upper and lower plates are investigated by using the waveguide finite and boundary element method. The interaction between the structural and acoustic waves propagating along the double-layered strip plate is investigated by observing the dispersion relations of the waves. T...

Exact solutions are derived for three-dimensional, anisotropic, linearly magneto-electroelastic, simply-supported, and multilayered rectangular plates under static loadings. While the homogeneous solutions are obtained in terms of a new and simple formalism that resemble the Stroh formalism, solutions for multilayered plates are expressed in terms of the propagator matrix. The present solutions...

This research employs a nondestructive, rapid, high accuracy and full-field material characterization platform which integrates quantitative laser ultrasound visualization system (QLUVS) with mechanical property mapping reconstruction algorithm. The QLUVS uses a pulsed laser generate acoustic waves with fast scanning mechanical to research two dimensional scanning goal and then detected with a ...

A simple model of the magnetoelectric (ME) effect in cylindrical layered composites is presented. The cylinder is replaced by the effective layered plate structure with effective length, Leff , thickness t and height h. In the axial coupling mode, the effective magnetic field acts along the length direction (Leff ). However, in the vertical coupling mode, the effective magnetic fields act in tw...

A finite element model is constructed to analyze the steady heat conduction and thermal stress in a ceramic/FGM/metal composite EFBF plate under convective heat transfer boundary. From numerical calculation, when 1   b a   , T0=Ta =300K and Tb=1 800K, the steady heat conduction and thermal stress distributions in the plate were obtained. The numerical results show that the temperature distr...

We study vibrations of singleand multi-layered rectangular graphene nanoribbons (GNRs) using molecular mechanics (MM) simulations by employing the MM3 potential. Two sets of boundary conditions are considered, namely, clamping atoms on either all four edges (CCCC) or on the two small edges (CFCF). Furthermore, we consider two scenarios for a single-layered GNR – one in which an interior atom is...
