FRICTION MODELING IN SIMULATING BALLISTIC IMPACT. A REVIEW

Blog Article

This paper presents a review on using friction coefficient in modelling ballistic impact.The are discussed telemarkskongen flue 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).Recent works simulating the impact projectile - target, done at different levels (micro, meso, macro) pointed out acure face lotion the influence of friction coefficient between bodies in contact.In all cited references, the friction coefficient is kept constant, even if experimental studies proved that it has different values for different sliding speeds, especially for contact metal - polymer as in the impact of aramid fabric armor.
