Depth of penetration of Dyneema® HB26 hard ballistic laminates

Abstract

Analysis of depth of penetration (DoP) experimental data of Dyneema® HB26 hard ballistic laminates is presented using an energy approach. Several DoP experimental parameters have been identified and calculated including the threshold velocity of penetration ([Formula: see text]), the characteristic time ([Formula: see text]), the DoP damping coefficient ([Formula: see text]), and the dynamic pressure per unit impact speed ([Formula: see text]). For the first time, a simple penetration model is developed from the energy approach to predict the projectile motion and penetration resistance force during depth of penetration experiments.
