An underwater explosion near the ships can happen in many situations. It can
devastate the ship’s readiness and can lead to the damage of ship structure shape.
This study is focused on the dynamic response of a model of ship structure that are
used as targets to investigate the damage of the ship model structures subjected to
near-field underwater explosion (UNDEX). The effects of both shockwave and bubble
oscillation are considered. Numerical modelling, using finite element method (FEM),
may provide information that looks into the details of the fluid model, dynamic
characteristics of the ship hull. The ship shocks modelling and simulation has been
performed by using an ABAQUS Explicit software. The displacements, velocities, and
accelerations of some testing point are investigated. Furthermore, the effects of the
mass proportional damping factor to the velocity response have been investigated
numerically. Finally, the analysis of ship damage subjected to an underwater explosion
is discussed.
