Abstract

In this paper, using the validated finite element models, a series of parametric study results of fibre metal laminates subjected to low velocity impact were presented. This covers influences of target size, target thickness, projectile size and projectile striking angle on the peak load and perforation energy. Based on these parametric study results and Timoshenko's theory, empirical formulas for circular or square plates impacted perpendicularly at the target centre by hemi-spherical projectile were developed. The calculated results from the empirical formulas were compared with experimental results and numerical simulations. Good correlation was obtained in terms of load-displacement traces up to the peak load and the peak load and perforation energy. The formulas developed may be used to assist design of fibre metal laminates subjected to low velocity impact.
