Perforation mechanism in stiffened plates
Numerical simulations were performed to examine the phenomena attendant to the perforation of truncated oval shape projectiles on stiffened plates. The effects of initial velocities, base plate thicknesses, height and width of stiffener on residual velocities were investigated. Dimensional analysis was employed to give an empirical formula and membership function was introduced to modify the empirical formula. The predictions of numerical simulations and empirical formula are in reasonably good agreement with those of experiment, which indicates that the finite element model and the empirical formula are capable of predicting the residual velocity of multi-layered stiffened plates.
