Steady-state Penetration Of Transversely Isotropic Rigid/perfectly Plastic Targets
Axisymmetric deformations of a transversely isotropic, rigid/perfectly plastic target being penetrated by a long rigid cylindrical rod with an ellipsoidal nose have been analyzed. The deformations of the target appear steady to an observer situated at the penetrator nose tip. The contact between the target and the penetrator is assumed to be smooth. Computed results show that the deformation field adjacent to the penetrator nose surface is significantly influenced by the nose shape, and the ratio of the yield stress in the axial direction to that in the transverse direction. The axial resisting force experienced by the penetrator is found to depend strongly upon the nose shape and the ratio of the yield stress in the axial to that in the transverse direction, but weakly upon the square of the penetration speed. © 1992.
