The design of light aircraft sandwich structures is driven by a local buckling phenomenon named “wrinkling” which can be the primary cause failure such structures. Structural tests using VERTEX methodology were performed to access wrinkling behaviour 558x536 mm 2 technological specimens representative used in aviation. operating principle machine use four hydraulic actuators load rectangular bo...

The last decade has witnessed the rapid development of aeronautical engineering including all branches of applied sciences and technology dealing with aircraft and their support systems, which brings forward the higher request of safety, efficiency, and environmental protection. Modeling, control, and optimization of aeronautical engineering have played an increasingly important role in meeting...

Corrosion in the aircraft industry continues to be a major problem that directly affects safety, costs, and availability [...]

Abstract. Labyrinth-shape quarter wavelength tubes are numerically studied under plane wave excitation, with analytical comparison. These labyrinth resonators (LRs) tuned at 60, 90 and 120 Hz, their sound absorption response exhibits maximum peak those frequencies high fidelity performance. objects can absorb tonal sources very low frequencies, an incredibly competitive thickness, resulting in ...
