Impact behavior of low strength projectiles
Witryna7 paź 2024 · Abstract. Accurate assessments of rebound velocity of a projectile in impact events for ceramic matrix composites (CMCs) are important since the rebound velocity affects the degree of resultant impact damage in both CMC targets and projectiles. A series of in-depth characterizations of coefficients of restitution (COR), which is … Witrynawhere f c ′ = compressive strength of concrete (Pa); h = thickness of target (m); ρ c = density of concrete (kg / m 3); k = factor related to the target thickness and the diameter of the projectile; and I = impact factor.. Hwang et al. compared impact energy with resistant energy to estimate the penetration depth and residual velocity of the …
