The vibration attenuation mechanism of shear thickening fluid- (STF-) filled sandwich structures was investigated in this study. Structural equivalent damping, stiffness, and mass increased simultaneously with the increase volume fraction fluid. However, damping ratio decreased natural frequency structural mass. Thus, not a monotonically increasing function STF. A modified strain model layer de...

This paper studies acoustic emission (AE) wave propagation in a glass fibre aluminium honeycomb sandwich panel (HSP). Of particular novelty is the quantification of through-thickness AE from one surface HSP to other, which real-world monitoring consideration for applications where instrumentation only be permissible on surface, i.e. aerofoils. Complexity was introduced specimens stages enable t...

The mechanisms of failure a composite sandwich structure subjected to projectile impact have been investigated. results reveal the complex interplay between various damage dissipation mechanisms. effects modifying matrix skins with polysiloxane core–shell rubber (CSR) nanoparticles and silica were Single cantilever beam specimens tested evaluate skin-core debonding. addition CSR beyond 3 wt% ca...

in this research work nano porous silicon layers with different porosity were prepared by using electrochemical etching. surface morphology and size of pores were investigated by scanning electron microscopy (sem).tio2 thin films with ebpvd method have been deposited on the surface of psi layers. the influence of anodization conditions such as anodization time interval and current density on el...

We perform a comprehensive first-principles study of the electronic properties of van der Waals (vdW) trilayers via intercalating a two-dimensional (2D) monolayer (ML = BN, MoSe2, WS2, or WSe2) between a MoS2 bilayer to form various MoS2/ML/MoS2 sandwich trilayers. We find that the BN monolayer is the most effective sheet to decouple the interlayer vdW coupling of the MoS2 bilayer, and the resu...
