Dz. Yankelevsky, LOCAL RESPONSE OF CONCRETE SLABS TO LOW-VELOCITY MISSILE IMPACT, International journal of impact engineering, 19(4), 1997, pp. 331-343
A new model to predict the penetration and perforation of concrete sla
bs impacted by low velocity missiles, is presented. The two-stage mode
l incorporates a first stage penetration algorithm into an infinite me
dium and a second stage of punching shear. The transition between stag
es is determined and the penetration time history as well as concrete
plug shear resistance and shape are calculated. The present model pred
ictions are compared with several common formulae as well as with test
data and good agreement is obtained. (C) 1997 Elsevier Science Ltd.
