Accelerated fully coupled hydro-elastic analysis of ships based on modal matrix reduction

Abstract

Hydro-elastic effects such as springing, whipping and racking can significantly increase hull stresses and fatigue damage. However, fully coupled time-domain hydro-elastic simulations remain computationally prohibitive for practical ship design due to the high cost of the structural solver.

Objective: Develop an efficient two-way coupled hydro-elastic framework capable of capturing resonance effects with full-length detailed structural models, while drastically reducing computational cost.
