Glass Fracture Upon Ballistic Impact: New Insights From Peridynamics Simulations [PDF]

Frontiers in Materials, 2019
Most glasses are often exposed to impact loading during their service life, which may lead to the failure of the structure. While in situ experimental studies on impact-induced damage are challenging due to the short timescales involved, continuum-based ...

Experimental tests and numerical simulations of ballistic impact on laminated glass [PDF]

EPJ Web of Conferences, 2021
In this study, we investigate double-laminated glass plates under ballistic impact through experimental tests and numerical simulations. The experimental tests are used to determine the ballistic limit velocity and curve for the laminated glass targets ...

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 ...

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.
