The anomalous behavior of coefficient of normal restitution in the oblique impact [PDF]

, 2004
The coefficient of normal restitution in an oblique impact is theoretically studied. Using a two-dimensional lattice models for an elastic disk and an elastic wall, we demonstrate that the coefficient of normal restitution can exceed one and has a peak ...

Finite element modelling and experimental study of oblique soccer ball bounce [PDF]

, 2011
In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us

Evaluation of local damage to reinforced concrete panels subjected to oblique impact - Simulation analysis for evaluating perforation phenomena caused by oblique impact of deformable projectiles -

Mechanical Engineering Journal, 2018
To date, oblique impact has not been studied and few experimental data on the local damage of reinforced concrete (RC) panels exist for oblique impact of deformable projectiles.

Impact Ejecta near the Impact Point Observed using Ultra-high-speed Imaging and SPH Simulations, and a Comparison of the Two Methods

, 2020
High-speed impact ejecta at velocities comparable to the impact velocity are expected to contribute to material transport between planetary bodies and deposition of ejecta far from the impact crater.

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

A numerical study on the impact behavior of foam-cored cylindrical sandwich shells subjected to normal/oblique impact

Latin American Journal of Solids and Structures
Finite 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 ...

Coulomb explosion sputtering of selectively oxidized Si [PDF]

, 2009
We have studied multiply charged Arq+ ion induced potential sputtering of a unique system comprising of coexisting Silicon and Silicon oxide surfaces. Such surfaces are produced by oblique angle oxygen ion bombardment on Si(100), where ripple structures ...
