Failure and impact behavior of facade panels made of glass fiber reinforced cement(GRC) [PDF]

, 2011
GRC is a cementitious composite material made up of a cement mortar matrix and chopped glass fibers. Due to its outstanding mechanical properties, GRC has been widely used to produce cladding panels and some civil engineering elements.

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

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).

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 ...

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

Numerical modeling and analysis of the ballistic impact response of ceramic/composite targets and the influence of cohesive material parameters

International journal of damage mechanics, 2021
Hybrid ceramic/composite targets are acknowledged to provide effective impact protection against armor piercing projectiles, which is why the research on this topic is continuously developing further. In this work, a nonlinear dynamic finite element (FE)

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 ...
