The dependence of penetration velocity on impact velocity

International Journal of Impact Engineering, 2006
Abstract Recent experimental measurements show that eroding long-rod penetration velocity is a linear function of impact velocity over a very wide range of impact velocities and for an interesting range of rod–target material combinations. These experiments all show that U = a + bV , where U and V are the penetration and impact velocity ...

Analysis of low velocity frontal impacts

Clinical Biomechanics, 2003
The objectives of the study were to determine the phasic recruitment of cervical muscles with increasing magnitudes of low velocity frontal impacts, and to determine quantitative effects of awareness of impending impact in comparison to being impacted unawares.Biomechanics of low velocity frontal impact is poorly understood and requires more work.Ten ...

Velocity scaling impact melt volume

International Journal of Impact Engineering, 1987
Abstract Velocity scaling relationships for the amount of melted target material produced by hypervelocity impacts are examined. Scaling of the melt volume with nearly the momentum of the impactor has been obtained by Gault and Heitowit using a semi-analytical energy balance approach and energy scaling has been obtained from scaled hydrocode output ...

Velocity dependence of impact fluorescence

International Journal of Impact Engineering, 1997
Abstract When a hypervelocity projectile with velocity, v , strikes a target, there is a visible flash of impact fluorescence. If the radiation and the material are in thermodynamic equilibrium, the “intensity”, I , of the light obeys the power law, I ∼ v n .

Composite materials response under low-velocity impact

Composite Structures, 1984
Abstract A simple model, based on energy considerations, has been tested to predict the maximum contact force during a low-velocity impact between an impactor and a composite plate. Three different composites, i.e. glass cloth-polyester, carbon cloth-polyester and nylon cloth-polyester, were examined.
