Ground vibration propagation and attenuation of

These researches not only obtain the ground vibration amplitudes of different vibration sources but lucubrate the vibration attenuation measures of the construction vibration [6, 20]. Because the environmental influence generated by the vibration of roller is weaker than that of other vibration sources, research findings concerning vibration of roller are still rare.

Dynamical analysis of wind turbine blades based on

As the power of large wind turbines continues to increase, the length and flexibility of wind turbine blades continue to increase, and the blades are prone to vibration. Large amplitude vibrations can cause large dynamic stresses and accelerate the fatigue of the blade material, and even cause blade breakage.

Free vibration analysis of hybrid laminated plates

This paper studies the free vibration behavior of hybrid laminated plates using a layer-wise formulation. The laminated structures are made of graphite fiber-reinforced composite (GFRC) and multilayer functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plies. The internal single-walled carbon nanotubes (SWCNTs) are distributed in layer-wise form along the ply thickness

This readily scalable production method allows for more than 5 wt % of natural graphite (NG) to be directly exfoliated into FLG/GNP and dispersed in an epoxy resin. The in situ exfoliated graphitic nanoplatelets, with average aspect ratios of 300–1000 and thicknesses of 5–17 nm, were demonstrated to conferee exceptional enhancements in mechanical and electrical properties to the epoxy resin.

The effect of carbon fibers distribution on fracture behavior

2019/7/10Therefore, when the amplitude is too large and the CFs are unevenly distributed in the matrix, the fiber bundle pullout is the main fracture mode of the composite material. In this case, CFs cannot uniformly bear all loads during the stretching process, which would seriously affect the mechanical properties of the composites, as shown in figure 4 .
