Recent results on fluid–structure interaction for plates subject to high intensity air shocks are employed to assess the performance of all-metal sandwich plates compared to monolithic solid plates of the same material and mass per area. For a planar shock wave striking the plate, the new results enable the structural analysis to be decoupled from an analysis of shock propagation in the air. Th...

In order to meet the ever-increasing demand for high-strength, lightweight aerospace structures, a new material is created via combination of three prior innovations: sandwich configurations, composites, and the addition of carbon nanotubes. A theoretical sandwich panel is created using facesheets of a novel woven microfibre composite reinforced by carbon nanotube forests, as created by Vinod P...

This work presents a magnetron with sputtering unit (sandwich target). The novel-$$$ty of the is due to three parallel plates different metals included in unit. They are mounted on same axis and rigidly attached it. located reactive environment consisting plasma-forming argon gas (nitrogen, oxy-$$$gen, etc.). lower plate cold, while middle outer ones operate hot target mode. In erosion zone pla...

The two Non-Destructive Evaluation [ NDE ] techniques viz., Air Coupled Ultrasonic [ACU ] and Pulsed Thermography [PT ] find many applications in aerospace industry . These NDE techniques can be used for debond detection in spacecraft structural components like honeycomb sandwich deck plates, shear web panels and central cylinder made of aluminum core and composite face sheets. The Air coupled ...

In this paper, a refined plate theory is applied to investigate the free vibration analysis of functionally graded nanocomposite sandwich plates reinforced by randomly oriented straight carbon nanotube (CNT). The refined shear deformation plate theory (RSDT) uses only four independent unknowns and accounts for a quadratic variation of the transverse shear strains across the thickness, and satis...
