Meshless modelling of dynamic behaviour of glasses under intense shock loadings: application to matter ejection during high velocity impacts on thin brittle targets [PDF]

, 2006
The purpose of this study is to present a new material model adapted to SPH modelling of dynamic behaviour of glasses under shock loadings. This model has the ability to reproduce fragmentation and densification of glasses under compression as well as ...

Extreme-value statistics from Lagrangian convex hull analysis for homogeneous turbulent Boussinesq convection and MHD convection [PDF]

, 2017
We investigate the utility of the convex hull of many Lagrangian tracers to analyze transport properties of turbulent flows with different anisotropy. In direct numerical simulations of statistically homogeneous and stationary Navier-Stokes turbulence ...

Ballistic Performance Evaluation of Aluminium Plate Impact by Fragment Simulating Projectile

Journal of Physics: Conference Series, 2020
Abstract The ballistic performance has drawn attention to researchers from a military background. They intend to provide solutions to ensure the soldiers in the front line of war do not kill in action. A casualty in war can lead to depression among soldiers and not to mention to their family as well.

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

Advanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Mechanical analysis of helmeted headforms under ballistic impact with implications in performance evaluation of ballistic helmets

Frontiers in Mechanical Engineering, 2023
Behind helmet blunt trauma is a significant health concern in modern warfare. The ballistic response of the human head under ballistic impact is highly sought. Towards this end, we conducted ballistic experiments on three different headforms.

Revisiting the distance to the nearest UHECR source: Effects of extra-galactic magnetic fields

, 2020
We update the constraints on the location of the nearest UHECR source. By analyzing recent data from the Pierre Auger Observatory using state-of-the-art CR propagation models, we reaffirm the need of local sources with a distance less than 25-100 Mpc ...
