TL;DR: In this article, the impact of a cylindrical hard steel projectile, weighing 120 g, with a conical nose and a 1.5 aspect ration, on regular strength concrete and high strength concrete (HSC) plates, with the following reinforcement: 5 mm steel mesh, steel fibers, small diameter steel wire mesh, and woven steel fence mesh of various diameters.

12 Nov 1982TL;DR: In this paper, a bi-axial support of a rotatable body in a fixed part having the open end directed forwards in the motion direction of a moving object is proposed, where the spherical bearing body is retained in the recess by two pairs of link arms defining two virtual tilting axes for the bearing body and connected to two output shafts such that a tilting motion of the body about the respective virtual axis results in a rotation of the respective output shaft and vice versa.
Abstract: The invention relates to a bi-axial support of a rotatable body in a projectile for supporting said body such that it can perform small tilting motions about two mutually perpendicular axes lying in a plane, which is perpendicular to the longitudinal axis of the projectile. The support consists of a spherical or partly spherical bearing body introduced into a correspondingly spherical cup-shaped recess in a projectile-fixed part having the open end directed forwards in the motion direction of the projectile. The spherical bearing body is retained in the recess by means of two pairs of link arms defining two virtual tilting axes for the bearing body and connected to two output shafts such that a tilting motion of the body about the respective virtual axis results in a rotation of the respective output shaft and vice versa. When firing the projectile the spherical surface of the bearing body comes in metallic contact with the spherical surface of the recess, whereby the support can withstand very high acceleration forces in any direction.

TL;DR: In this paper, the effect of projectile nose shape, impact velocity and plate thickness on the deformation of the target plates was studied and a finite element analysis of the problem was carried out using ABAQUS finite element code.
