Time-Resolved Penetration of B$_{4}$C Tiles by the APM2 Bullet

A modification of Wilkins computational ceramics model is used to simulate experiments of the impact of the APM2 bullet against boron carbide/aluminum targets. Flash radiography provides timeresolved penetration histories. The simulation results are compared to the experimental data; generally, agreement is very good, including capturing dwell and then the onset of penetration. Crater width and debris diameter are also reproduced by the simulations reasonably well. A critical discussion of deficiencies of this computational engineering model is provided. keyword: ceramic modeling, dwell, boron carbide, APM2 bullet, ceramic tile, numerical simulations, constitutive modeling, time-resolved data
