✦ Synopsis

The contact law and impact response of a carbon-epoxy laminated composite plate subject to an impact of a rigid bullet-like steel cylinder projectile were investigated analytically and experimentally. The contact law for the laminated composite plate and the steel projectile was established by performing the static indentation test. The indentations and the contact forces were measured to establish the contact law by using the method of least squares. The effects of the laminate thickness and ply orientations on the contact law were also conducted. The contact law of the laminated plate was mathematically modeled and incorporated into a three dimensional hybrid stress finite element program to predict the impact response of the laminated carbon-epoxy composite plate when impacted by a projectile.
