Description/Abstract

A two-dimensional hydroelasticity analysis for the symmetric (i.e. vertical motions and distortions) dynamic behavior of ships in waves, including the influence of nonlinearities, is presented in this paper using two methods based on direct integration and convolution integration methods. The influence/ importance of flare slamming, bottom impact and green water, nonlinear hydrodynamic forces due to changes in added mass and damping coefficients as well as restoring and incident wave forces are investigated. The method is illustrated for the S-175 containership. Comparisons made between predictions and experimental measurements indicate good overall agreement. The comparisons also show that the influence of flare slamming is important for the range of speeds and wave amplitudes investigated.
