Damage Analysis on Woven Randomly Composite Plates

Abstract

In this study, dynamic analysis of woven randomly composite plates with different impact damage patterns including pattern of post-low velocity impact and patterns of post-ballistic impact is considered. For this purpose, modal testing procedure is performed to present the vibration characteristics of the clamped-free square plates. Effects of bullet-tip geometry, projectile velocity, and impact damage location on the vibration characteristics are examined experimentally. Mass effect is also investigated for this purpose. Results are given in tabular and graphical form.
