FRICTION MODELING IN SIMULATING BALLISTIC IMPACT. A REVIEW

open access: yesProceedings 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).
