Outline of Final Research Achievements

The floating/fixed ocean structures such as wind power plants and other structures on offshore have to be taken account of safety in rough sea and tsunami. It is necessary to predict behaviors for both structures and fluid.
The smoothed particle hydrodynamics (SPH) method which is one of the particle methods is applied to some problems of fluid dynamics and solid mechanics. The SPH methods are mainly utilized to a number of problems for the fluid dynamics. If the structures in the ocean will be subjected to the large deformation from the waves, the stress may exceed the yield stress in the structures. The elastic-plastic effects have to be taken into account for the behavior of the structures. The stability terms are included for the open source software SPHysics for fluid analysis. Analyses of the mooring and floating structures are carried out by the SPH method and The vortex method.
