Hydrodynamics of the stream-disk impact in interacting binaries [PDF]

, 1997
We use hydrodynamic simulations to provide quantitative estimates of the effects of the impact of the accretion stream on disks in interacting binaries. For low accretion rates, efficient radiative cooling of the hotspot region can occur, and the primary

A Study of the Ballistic Limit of AA2024-T351 Sheets Impacted by Spherical and Cubical Compact Projectiles

Engineering Transactions, 2016
This paper presents the results of an investigation of the ballistic limits and failure modes of AA2024-T351 sheets impacted by spherical and cubical projectiles. The investigation included a series of impact experiments and numerical simulations.

FRICTION MODELING IN SIMULATING BALLISTIC IMPACT. A REVIEW

Proceedings on Engineering Sciences, 2019
This paper presents a review on using friction coefficient in modelling ballistic impact. The are discussed on friction introduced in modelling the impact at different levels: micro (fiber and yarns), meso (woven or unidirectional fabrics) and macro (layered or equivalent monoblock structures).

Simulation-Based Assessment of Rear Effect to Ballistic Helmet Impact [PDF]

Computer-Aided Design and Applications, 2010
AbstractBallistic impact is one of the major causes for traumatic brain injury (TBI) and ballistic helmets are designed to provide protection from TBI. In real life, it is impossible to use real human subjects for experiments. Therefore, simulation based-methods are convenient to assess the rear effect to ballistic helmet impact and can provide crucial

Effect of stress triaxiality cut-off value in the fracture criterion on predicting the ballistic behavior of Al2024-T351 plate impacted by blunt- hemisphere- and ogival-nosed projectiles

Journal of Materials Research and Technology, 2023
Finite element analysis has been carried out to study the effect of stress triaxiality cut-off value in the fracture criterion on the ballistic behavior of 9.94 mm thick Al2024-T351 plates impacted by rigid blunt-, hemisphere- and ogival-nosed ...

Influence of yield-surface shape in simulation of ballistic impact [PDF]

International Journal of Impact Engineering, 2017
Abstract A high-exponent yield criterion is applied in 3D nonlinear finite element simulations of ballistic impact. The computational models are based on a comprehensive experimental study including material tests of 12 mm thick high-strength Weldox 700 E steel plates and ballistic tests where the plates were struck by blunt-nosed and ogive-nosed ...

Combining protective clothes with human body models for finite element ballistic impact simulations

Communications in Development and Assembling of Textile Products, 2023
The ballistic deformation of an ultra-high-molecular-weight (UHMW) polyethylene (PE) composite has been subjected numerically to a multi-layered soft ballistic fabric package modelled upon the body contours of the Global Human Body Models Consortium ...

Optimisation of ballistic protection systems based on impact test/simulation correlation [PDF]

EPJ Web of Conferences, 2021
The complexity of ballistic protections increases with their efficiency. On this basis, an exclusively empirical approach is not adapted to optimise complex protection systems and the resort to numerical simulations is preferred if not mandatory. The present study proposes a methodology aiming at optimising complex multi-layer ballistic armours based ...
