摘要：

This paper presents Lagrangian EPIC code computations for oblique, yawed-rod impacts onto thin-plate and spaced-plate targets at various velocities. The baseline set of computations considers a nominal obliquity of 65 degrees and a nominal impact velocity of 1300 m/s, onto thin-plate targets at nominal yaw angles of 0, -10 and +10 degrees. The yaw angles are achieved by inducing velocities into the plates. These results are compared to test data and MESA code results published previously. Additional sets of computations are presented to show the effect of increased impact velocities at nominal values of 2600 m/s and 5200 m/s. Some spaced-plate computations are also included.
