Dynamic response of high-speed craft bottom panels subjected to slamming loadings

Abstract The inelastic deformation of a 30 m high-speed craft (HSC) subjected to slamming pressure is the main topic this research. In work, commercial software package ABAQUS FEA used predict structural behavior, especially in hull area under chine. Dynamic explicit solver simulations are done plastic deformation. Before principal analysis actual size ship structure model, numerical studies were validated against relevant experimental data from previous open literature. A reassessment design guidelines was also forecast load on HSC structure. Then, with increased limit, parametric conducted two different idealizations type: rectangular and triangular. Finally, study identifies variables that must be considered when calculating degree brought by loads.
