A non-linear time-domain strip theory for vertical wave loads and
ship responses is presented. The theory is generalized from a
rigorous linear time-domain strip theory representaton. The
hydrodynamic memory effect due to the free surface is approximated
by a higher order differential equation. Based on this time-domain
strip theory, an efficient non-linear hyroelastic method of wave-
and slamming-induced vertical motions and structural responses of
ships is developed, where the structure is represented by the
Timoshenko beam theory. Numerical calculations are presented for
the S175 Containership and are systematically compared with the
experimental results given by Watanabe et al. and O'Dea et al. The
agreement between the present predictions and the experiments is
very encouraging.
