Experimental investigation of normal perforation of projectiles in metallic plates

Analysis of the Mechanics of Normal Perforation of Metallic Plates by High-Speed Projectiles

“…For both rigid and deformed proj ectiles, the curves show that the velocity drop AV decreases beyond the ballistic limit and sli ghtly increases ag ain with the increase of impact velocity. These results are consistent with those of other investig ators such as Liss and Goldsmith [14] and Awerbuch and Bodner [15].…”

An investigation of oblique perforation of metallic plates by projectiles

“…A detailed description of the test procedure is given in (2]. The geometrical parameters of the cavity, i.e., entrance and exit shapes, were measured after each test.…”

“…In order to obtain more information on the process of oblique perforation, the photographic equipment described in (2] was modified for multiple (triple) exposures at prescribed time intervals. Three stroboscopes (Genera Radio Types 1531, 1538A, and 1539) and auxiliary equipment were combined with three delay units for this purpose.…”

Separation and velocity dependence of the drag force applied to a rigid ovoid of Rankine nosed projectile penetrating an elastic–perfectly-plastic target

“…A number of theoretical approaches to penetration mechanics have been proposed. These include: hydrodynamic models which neglect yield strength [3][4][5]; models which use a modified Bernoulli equation that includes yield strength approximately [6][7][8]; onedimensional models based on a balance of rate of work and rate of energy dissipation [9][10][11]; models based on the contact pressure for spherical or cylindrical cavity expansion [12][13][14][15][16][17][18][19][20][21]; models based on approximate flow fields [22][23][24][25][26][27][28]; and full numerical simulations [29][30][31][32].…”
