FLUID-STRUCTURE INTERACTION PROBLEM WITH COMBINED SMOOTHED PARTICLE METHOD AND FINITE ELEMENT METHOD

Combining the SPH (Smoothed Particle Hydrodynamics) method for the fluid simulation and the standard FEM (Finite Element Method) for the structure simulation, robust numerical model for the simulation of fluid- structure coupled problems have been developed. The model is primarily developed for simulation of steel structures that are in contact with liquid and can be described by shell elements (water tanks, reservoirs, etc.). The model can be used to describe the main nonlinear characteristics of the construction steel: flow (yield) under compression and tension and evolvent of plasticity. It is also possible to simulate the basic nonlinear characteristics of the fluid (compressibility, viscous flow and turbulence).
