Tungsten long-rod penetration into confined cylinders of boron carbide at and above ordnance velocities

Modeling shear instability and fracture in dynamically deformed Al/W granular composites

“…Details of the model are presented in [15]. Material constants used were taken from open literature [16][17][18].…”

Transition between interface defeat and penetration for tungsten projectiles and four silicon carbide materials

“…This phenomenon, called interface defeat and first reported by Hauver et al [1][2][3], has been investigated at FOI since the middle of the 1990s [4][5][6]. By use of a reverse impact technique [7] and targets with initially constrained ceramic cylinders (shrink-fitted in a steel sleeve) it has been shown that, for a given cylindrical projectile, ceramics of different types (e.g., titanium diboride and boron carbide) are characterized by different velocities, called transition velocities, that mark the transition between interface defeat and penetration [6].…”

The effect of thin membrane restraint on the ballistic performance of armor grade ceramic tiles

“…Lundberg et al [14] and Westerling at al. [15] also studied the phenomenon of dwell and the effect of penetration velocity on the transition between dwell and inception of penetration.…”
