Numerical Simulation of Microscale Oblique Droplet Impact on Liquid Film
Aerospace, 2023 The oblique impact of microscale water droplets on liquid film is numerically investigated. Two-phase flow problems are simulated using three-dimensional incompressible Navier-Stokes equations, and the level-set method is employed for capturing the gas ...

Azimuthal impact directions from oblique impact crater morphology [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 Planetary impact craters have a high degree of radial symmetry. This hampers efforts to identify the azimuthal impact direction for most craters - the radially symmetric component of an impact crater swamps any asymmetries that may be present. We demonstrate how the asymmetric component can be isolated and the direction of the asymmetries quantified ...

Projectile preservation during oblique hypervelocity impacts [PDF]
Meteoritics & Planetary Science, 2018 AbstractImpact angle plays a significant role in determining the fate of the projectile. In this study, we use a suite of hypervelocity impact experiments to reveal how impact angle affects the preservation, distribution, and physical state of projectile residues in impact craters.

Penetration of sandwich plates with hybrid-cores under oblique ballistic impact
Theoretical and Applied Mechanics Letters, 2014 The oblique penetration performance of lightweight hybrid-cored sandwich plates are investigated numerically. To compose the hybrid-core, ceramic prisms are inserted into pyramidal metal lattice trusses and fixed using epoxy resin.

Impact simulations on local damage of reinforced concrete panel influenced by projectile nose shape
Mechanical Engineering Journal, 2020 Most impact research has been presented on the basis of impact tests and numerical analysis performed by rigid projectile impact perpendicular to the target structure. On the other hand, there are only few reports on impacts at an oblique angle.

Oblique Impact on Crashworthiness: Review
International Journal of Engineering Technology and Sciences, 2017 This paper reviewed the crashworthiness of foam-filled thin-walled structure subjected to oblique loading conditions. Crashworthiness is the most important part in designing a safety vehicle, so, the types of collisions, crashworthiness parameter and the modes of collapse of structural components are included in this part. Secondly, the energy absorber

Latin American Journal of Solids and StructuresFinite element analysis was used to investigate the impact behavior of the foam-cored sandwich shells under the ballistic impact. The ballistic limit, failure mode of the face-sheet and energy absorption of the uniform/graded core were discussed in this ...
