Hydroelasticity caused by water impact is of concern in many applications of
ocean engineering/naval architect and a complicated physical phenomenon. We have
developed a coupled Eulerian scheme with Lagrangian particles to combine advantages and to
compensate disadvantages in both grid based method and particle based method. In this study,
the developed numerical model was applied to hydroelastic problems due to impact pressure
such as water entry of an elastic cylinder and elastic tanker motion in wave. We showed the
numerical results which is overall agreement with experimental results
