FRICTION MODELING IN SIMULATING BALLISTIC IMPACT. A REVIEW

Blog Article

This paper presents a diamond painting strand en zee 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).Recent works simulating the impact projectile - target, done at different here levels (micro, meso, macro) pointed out 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.
