Sažetak
This investigation is related to the natural vibration analysis of bottom and vertical plate structures in contact with fluid using the assumed mode method. The procedure can consider thick plates and stiffened panels, where the Mindlin theory is adopted for a plate and Timoshenko beam theory for the stiffeners. The eigenvalue problem is formulated using Lagrange's equation of motion and taking into account potential and kinetic energies of a plate structure and fluid kinetic energy, respectively. Potential flow theory assumptions are adopted for the fluid and the effect of free surface waves is ignored. From the boundary conditions for the fluid and structure the fluid velocity potential is derived and it is utilized for the calculation of added mass using the assumed modes. Based on the developed theoretical background, the in-house software is developed and applied to the vibration analyses of plates and stiffened panels in contact with fluid with different domain sizes and various sets of boundary conditions. Comparisons with FEM-BEM numerical results show high accuracy of the proposed procedure.
