In a number of applications, the hydrodynamic effect of a fluid must be included in the structural evaluation of liquid filled vessels undergoing transient loading. Prime examples are liquid radioactive waste transportation packages which must demonstrate the ability to withstand severe accidental impact scenarios. A hydrodynamic model of the fluid is developed using a finite element discretization of the momentum equations for a three dimensional continuum. An inviscid fluid model with an isotropic stress state is considered. A bartropic equation of state, relating volumetric strain to pressure, is used to characterize the fluid behaviour. The formulation considers the continuum as a compressible media only, so that no tension fields are permitted. The numerical technique is incorporated into the existing Ontario Hydro general purpose three dimesioanl structural computer code H3DMAP. Part 1 of the paper describes the theory and implentation along with comparisons with classical theory. Part 2 describes the experimental validation of the theoretical approach. Excellent correlation between predicted and experimental results is obtained.
