Abstract: (6305 Views)
Investigation of projectiles penetration phenomenon has been carried out in non-cohesive soil (Sand) targets under dry, saturated and compacted conditions. Analytical studies have been performed on the linear and non-linear soil models to obtain penetration depth formulae for ogival nose projectile and the results are verified by experimental studies. In present work, three ogival nose projectiles each having weight of 1.0 kg and nose angle of 15o, 30o and 45o are dropped from a height of 10.0 m in rectangular tank filled up by non-cohesive soil target. The rigid projectiles made an impact on a uniform target material at normal incidence with striking velocity of 14 m/s and proceeded to penetrate at rigid-body velocity. The models require geometrical parameters of the projectile types, velocity and target shear strength for the overall penetration depth of projectile. In addition, some parametric studies have been also carried out for academic and field interest.
