摘要: This paper presents a procedure to optimize conceptual ship side structure from crashworthiness point of view. As an example, this is presented for chemical or product tanker. A particle swarm optimization algorithm used the procedure. The classification society compliance design checked through service loads that are applied ship's hull girder according Det Norske Veritas. collision simulations assess carried out with non-linear finite element solver LS-DYNA. An length-dependent constant-strain failure criterion chosen simulate rupture. numerical simulation stiffened plate serves validate material relation until failure. and definition makes possible accurate prediction structural energy absorbed inner adjustable applicable other types scenarios.
