Numerical investigations on the sabots discard process of an APFSDS at different angles of attack

The Journal of Engineering, 2018
Sabot asymmetric discard after the projectile being launched from the muzzle at various angles of attack and 4Ma is investigated. This is implemented by the coupling computational fluid dynamics (CFD) and six degrees-of-freedom exterior ballistic code ...

Prandial Effects on Intravoxel Incoherent Motion Quantification in the Liver

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of detecting prandial (i.e., meal) induced changes in microvascular flow in the liver, including changes in the spatial distribution of flow velocities, using intravoxel incoherent motion (IVIM) MRI. Methods Thirteen (n = 13) healthy volunteers underwent two liver MR exams: one preprandial after fasting and ...

Hitting a bullet with a bullet: an analysis of colliding bullets using experimental data and explicit simulation methods [PDF]

Royal Society Open Science
A method to simultaneously fire and achieve a nose-to-nose collision of two bullets was created and compared to simulated results. This research focused on symmetric Taylor impact test techniques applied to 45-caliber Hornady 45177 full metal jacket (FMJ)

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Asymmetric transferability of trait–environment relationships between native and exotic plant species in Singaporean forests differing in land‐use history

Oikos, EarlyView.
Functional traits allow ecologists to synthesise general rules of community assembly. In joint species distribution modelling, traits are increasingly used to explain species–environment relationships, with the intention of being able to generalise predictions to other species in other systems.

The use of human tissue surrogates in anatomical modeling for gunshot wounds simulations: an overview about “how to do” experimental terminal ballistics

Frontiers in Bioengineering and Biotechnology
Human tissue simulating materials are currently used in scientific research mainly because they help to avoid possible ethical issues, unlike what happens with studies involving live animals and/or human cadavers.

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...
