Glass Fracture Upon Ballistic Impact: New Insights From Peridynamics Simulations

open access: yesFrontiers 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 ...

Ballistic Impact Experiments and Modelling of Sandwich Armor for Numerical Simulations

open access: yesProcedia Engineering, 2014
AbstractIn this paper some experimental results of a bullet impact on composite armor are discussed together with numerical modeling approaches. The development of high-quality composite sandwiches for ballistic protection is the target of a grant project in terms of which the research is being conducted.

Simulation on a Composite Laminate Subjected to Ballistic Impact [PDF]

open access: yesAdvances in Physics Research, 2014
A finite element model was developed to study the damage mechanisms of composite laminates under high velocity impact conditions. Modified Hashin failure criteria were used for the fiber breakage prediction. Cohesive elements were defined between two adjacent layers in the target laminate for the prediction of delamination initiation and propagation ...
