Abstract: | A general hydroelastic analysis formulation is presented by using Green's function. Emphasis is placed on the case of an incompressible fluid model which is applicable to flexible tank hydroelastic analysis. Variational formulation of the sloshing problem is established in order to obtain a numerical treatment by a mixed finite element method. A minicomputer program is illustrated and the hydroelastic analysis technique is checked as an efficient and accurate approach with some numerical solutions. |
