• Application study •
Penetration mechanics is important both as a science
and in practice of military engineering. For a quasi-steady penetration of long rod
projectile into semi-infinite thick target, a simplified model is
the bullet incorporated mushroom head consists of unbroken
zone, crush zone and hole dilating zone, and the target consists of hole
dilating zone, crush zone and unbroken zone, with the strain rate effect
considered. A set of ODE is obtained through conservation laws of every
part. Through theoretical analysis and calculation, the influences
of the crush strain rate, crash strength of the projectile and the
strain rate effect of the crash strength of the target on penetration depth
are analyzed. The excellent agreement of the calculation results and the
experiment shows the effectiveness of the simplified model.
