| Popis: |
We examined data from two sets of penetration experiments that recorded deceleration during penetration into concrete targets with compressive strengths of 23 and 39 MPa. The 76.2-mm-diameter, 13 kg projectiles contained a single-channel acceleration data recorder. We plotted deceleration versus displacement data and showed that this response could be closely approximated by a linear rise region with a depth of two projectile diameters followed by a tunnel region with constant deceleration until the projectile came to rest. A new empirical model predicts accurately the deceleration-displacement responses. |
