“…For example, if all other conditions are fixed, projectile reverse may occur at a critical oblique angle. Experimental [Rosenberg et al(2005)] and numerical [Dorogoy et al(2010)] investigations on oblique impact of polymethylmetracrylate plates, show that projectile reverse occurs for large angles of obliquity (60) when the plates are impacted by a 0.3" AP projectile with an impact velocity of 720 m/s.…”

Abstract:We present a general framework to describe the dynamics of a hard projectile penetrating into a solid target. Rigid-body dynamics, differential area force law and semi-empirical resistance function are used to formulate the motion of the hard projectile. The proposed model is capable of predicting the projectile trajectory under various oblique and yaw angles. Critical conditions for the occurrences of the instability and the reverse of the projectile trajectory are discussed. It was found that the relative location of mass centre of the projectile has strong influence on the control of the rotation of the projectile, and thus, the projectile stability and the change of trajectory direction. The validity of the proposed model is limited to deep penetration and when the wake separation and reattachment between projectile body and target have negligible influence on the target resistance to the projectile.

“…Recently published results revealed an intriguing capability of commercial polymethylmethacrylate (PMMA) panels to sustain and deflect ballistic impacts under certain conditions (Rosenberg et al, 2005). More generally, polymers are considered as potential components of armor systems, thus calling for a fundamental evaluation of their dynamic mechanical behavior.…”

“…장비 보호 및 인명 보호적인 측면에서 다양한 표적 체에 대해 발사체가 광범위한 속도를 갖고 충돌하는 경우, 보호물이 손상을 입는지의 판단이 상당한 관심 사가 되고 있다. 특히 발사체가 균일재료의 판재에 고 속으로 충돌하는 경우, 천공 및 도비(ricochet)현상을 포함하는 관통현상이 발생한다 1) . 이러한 관통현상 중 도비현상은 충돌하는 발사체에 중요한 고려사항 인자 중 하나이다.…”

:In this study, the numerical simulation using AUTODYN-3D program was investigated angle trajectory prediction for inclined impacts of projectiles. The penetration and perforation of polycarbonate plate by 7.62 mm projectile was investigated numerically. The characteristic structure of the projectile's trajectory in the polycabonate plates was studied. Two combined failure criteria were used in the target plate, and the target plate was modeled with the properties of polycarbonate for simulating the ricochet phenomenon. The effect of the angle of inclination on the trajectory and kinetic energy of the projectile were studied. The dynamic deformation behaviors tests of polycabonate were compared with numerical simulation results which can be used as predictive purpose. From the simulation, the ricochet phenomenon was occurred for angles of inclination of 0°≤ Ɵ ≤ 20°. The projectile perforated the plate for Ɵ ≤ 30°, thus defining a failure envelope for numerical configuration. The numerical analyses are used to study the effect of the projectile impact velocity on the depth of penetration (DOP). It can be observed that the residual velocities were almost linear relative to penetration velocities. It means that polycarbonate has high resistance at higher velocities.
