A fully-coupled quadratic strip theory/finite element method for predicting global ship structure response in head seas
This paper outlines the theoretical development and some validation of a quadratic strip theory method coupled to a global finite element model to predict the global structural response of the Korea Research Institute of Ships and Ocean Engineering (KRISO) hull geometry due to regular, head seas waves in the time-domain. The method attempts to capture some body-nonlinear effects of the dynamic problem due to time-varying underwater hull geometry by drawing a relationship between the coefficients, A33, B33, and C33 and the local draft, Ts. In addition, the hull girder is considered flexible and structural damping may be included. A segmented model test in head seas was also performed, and the linear and nonlinear numerical results are compared to the experimental data. It is found that the theory shows reasonably good agreement with the model test data, and that nonlinear effects account for a significant increase in predicted bending moment.
