Abstract: A study was conducted to examine the terminal effects of a 1.0-g steel RCC impacting 23 plies of KM2 fabric using the LS-DYNA Lagrangian hydrocode. The simulated impact velocities were 200, 400, 600, 800, 1000, 1200, and 1400 m/s. The fabric was a plain weave of 850 denier yarn. The LS-DYNA-simulated Vs versus Vr data points generated at the U.S. Army Research Laboratory (ARL) were compared to both experimental data and EPIC-generated data. Also, the LS-POST software package was used to view the simulated physical descriptions of the penetrator and target at various stages of the penetration process.
