dc.description.abstractHydro-elastoplastic analysis of floating plate structures subjected to time-dependent external loads is presented, in which elastoplastic material behaviors are coupled with linear surface gravity waves. Time-domain incremental coupled equations for the analysis are derived as formulating incremental equilibrium equations of floating plate structure and impulse responses functions associated with hydrodynamic pressures in the time domain. The present formulation can describe the interactions between fluids and structures with material nonlinearity. Also, a time-domain incremental nonlinear solution procedure is proposed. In the solution procedure, an implicit return mapping algorithm to simulate plastic behaviors of floating plate structures and a direct coupling method to construct frequency-wave inddependent metrics, which can be converted to IRFs by Fourier transformation, are employed. Through numerical examples of plate structures floating on the free surface of water, the capability and the performance of the proposed solution procedure are demonstrated.-
