Abstract : a previously proposed approximate quasi - static theoretical method is employed herein to examine the deformation and perforation of a simply - supported circular plate struck by a flat - faced projectile at normal incidence. based on the principle of virtual work, static load - displacement relationships are first obtained and then used to predict the energy - absorbing capacity of the plate subjected to relatively low speed impact. it is shown that good agreement is obtained between the theoretical predictions and the available experimental data, provided that adiabatic shear plugging failure does not occur, but the influence of strain rate sensitivity is taken into account
