Abstract

The transient response of an E-Glass / Vinyl-Ester composite material subjected to underwater explosive loading has been studied. The work consists of experimental testing, utilizing a water filled conical shock tube and computational simulations, utilizing the commercially available LS-DYNA finite element code. The composite plates are 0/90 biaxial laminates with a thickness of approximately 1.3mm. The plates are round disks with elliptically curved mid-sections. The transient response of the plates is captured in real time through the use of a Digital Image Correlation (DIC) system. The DIC data and computational results show a high level of correlation for both the out-of-plane deflection and velocity histories.
