Finite element analysis and optimization of foam filled fender under quasi static and dynamic responses

Mainly composed of elastic materials, ship fenders are utilised on all kinds vessels for the protection berthing structures and prevention damage due to heavy crash loads. This study aims enhance deformation mode performance foam-filled under quasi-static dynamic loadings. Six models fender’s structure chosen simulation test. The examined crashworthiness parameters such as crushing force efficiency (CFE) specific energy absorption (SEA). Finite element analysis is conducted estimating responses then compared an appropriate reference experiment result. Four design variables considered instance height, foam density, thickness, material optimization. Non-dominated Sorting Genetic Algorithm II multi-objective optimization approach used obtain maximum Specific Energy Absorption (SEA) minimum Crushing Force Efficiency (CFE). Based results optimization, best observed in model 5, however it can be replaced traditional fender design.
