The effect of varying ship proportions and hull materials on hull flexibility and on the concomitant bending and vibratory stresses for an ore carrier, a tanker, containership, and a general cargo ship is evaluated. With the flexibility of the ship's hull represented by the natural frequency of the ship associated with the two-node shape, a potentially useful relation between the flexibility and bending moment has been established. An analysis indicates that forward speed affects hydrodynamic damping and forces as well as hull flexibility, and there may exist an optimal flexibility for every ship, but there is not necessarily a limit to the flexibility.
