Research Abstract

A methodology to estimate the maximum local stress of a ship in slamming condition was proposed in this research. The calculation procedure consists of four levels ; the definition of the design short-term sea state and the design irregular wave, the estimation of nonlinear ship motion and distortion as a flexible beam in slamming condition, the estimation of nonlinear pressure distribution, and the stress analysis of the entire ship structure. The validity of the method was clarified from the viewpoint of ship structural design.
