TL;DR: In this article, the vibration analysis of uniform laminated composite sandwich beam with a viscoelastic core was studied and the governing equation of motion was derived based on higher order shear deformation theory (HSDT) in finite element model.
Abstract: In this paper, the vibration analysis of uniform laminated composite sandwich beam with a viscoelastic core was studied. The governing equation of motion of the laminated composite sandwich beam has been derived based on higher order shear deformation theory (HSDT) in finite element model (FEM). The developed finite element model has been validated in terms of natural frequencies with the experimental values and the available literature. Various parametric studies have been performed to examine the impact of the core thickness, ply orientation and aspect ratio of the uniform laminated composite sandwich beam in response to free vibration for various boundary conditions. From the results it was concluded that that natural frequencies could be increased with increasing the core thickness and decreased with increasing the aspect ratio.

TL;DR: In this article, the vibration behavior of aluminium alloy 5083-reinforced nanoclay andmontmorillonite nanocomposites was studied to have a better dynamic property for lightweight structural applications without affecting the mechanical property.
Abstract: In this work, vibration behaviour of aluminium alloy 5083-reinforced nanoclay–montmorillonite nanocomposites was studied to have a better dynamic property for lightweight structural applications without affecting the mechanical property. Composite samples with various weight percentages of nanoclay were fabricated using stir casting method and achieved uniform dispersion with strong interfacial bonding between matrix and reinforcement. The influence of nanoclay in the aluminium alloy composite was also studied by different material characterization techniques such as scanning electron microscope, energy-dispersive X-ray spectroscopy, X-ray diffraction and microhardness test. From the study, it was concluded that the microhardness value of the aluminium alloy-reinforced nanoclay was decreased with the increase in nanoclay weight percentage. The mechanisms related to the shifting of frequencies were studied to know the effectiveness of reinforcement. The natural frequencies of the aluminium alloy 5083-reinforced nanoclay composites were found to be increased with the addition of 2 wt% of nanoclay in comparison with AA 5083 and 1 wt% of nanoclay.

TL;DR: In this article, the dynamic behavior of composite beams reinforced by carbon nanotubes (CNTs) exposed to a mass moving is investigated by considering the external potential energy due to the applied moving mass, the equations of motion of the CNT-reinforced beam are obtained using Hamilton's principle by combining Reddy's third-order shear deformation theory and nonlocal strain gradient theory.
Abstract: In this study, the dynamic behavior of composite beams reinforced by carbon nanotubes (CNTs) exposed to a mass moving is investigated. By considering the external potential energy due to the applied moving mass, the equations of motion of the CNT-reinforced beam are obtained using Hamilton’s principle by combining Reddy’s third-order shear deformation theory and nonlocal strain gradient theory. Three types of aligned CNT-reinforced beams are considered, namely uniformly distributed CNT beams (UD-CNT) and functionally graded CNT beams type Λ (FGΛ-CNT), and type X (FGX-CNT). Navier’s procedure is applied to obtain the closed-form solutions of simply supported CNT-reinforced beams. Verification of the present solution with previous works is presented. A detailed parametric analysis is carried out to highlight the impact of moving load velocity, nonlocal parameter, material scale parameter, total volume fraction and CNTs distribution patterns on the midspan deflections of CNTs-reinforced composite beams. The proposed model is useful in the designing and analyzing of MEMS/NEMS, nanosensor, and nanoactuator manufactured from CNTs.

TL;DR: In this paper , a honeycomb core shape was proposed and compared with a normal hexagonal shape core in a sandwich beam, which has good flexural stiffness, resonance, fatigue, and stress resistance at higher frequency.
Abstract: The aim of this paper is to present a proposed honeycomb core shape and compare it with a normal hexagonal shape core in a sandwich beam. The sandwich cores are simulated in finite element with different materials; aluminum and epoxy-carbon with six layers are used as face sheet and the results are compared to those obtained theoretically. Simulation of 3-point bending test is performed in commercial software ANSYS to verify the analytical results with the numerical ones. Hence, for simplicity one layer of the skin is used on the equivalent model of sandwich for lesser computational time and more accurate evaluation. Simulation of harmonic analysis of hexagonal core and proposed core shape is carried out in frequency domain to identify the core with less deformation under high frequency and it can withstand harmful effects. The proposed core shape model having the same cell numbers and material as the normal hexagonal model is compared with experimental results; it is observed that the proposed core shape model has good flexural stiffness, resonance, fatigue, and stress resistance at a higher frequency.
