Numerical simulation of ballistic impact on composite laminates [PDF]

International Journal of Impact Engineering, 2005
Abstract The paper reports experimental and numerical simulation of ballistic impact problems on thin composite laminated plates reinforced with Kevlar 29. Ballistic impact was imparted with simulated fragments designed in accordance with STANAG-2920 on plates of different thickness.

Mechanical behavior of single-layer graphdiyne via supersonic micro-projectile impact

Nano Materials Science, 2022
The mechanical behavior of single-layer graphdiyne (SLGDY) subjected to high-velocity micro-ballistic impacts is analyzed by molecular dynamics (MD) simulations. The ballistic limits of SLGDY is obtained for the first time.

Failure simulation of stratified panel under ballistic impact

Journal of Engineering Sciences and Innovation, 2022
"This paper presents an analysis of an isothermal model for an impact simulation in order to use the results for virtually optimizing the thickness of the panel for the same threat. The target has a stratified structure; the connection between layers is ""bonded"", with ""breakable"" detachment when there is exceeded a value for tensile stress and ...

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 ...
