Abstract :
[en] The eigenfrequencies of a shell containing a liquid are modified by the static pressure of the fluid. This implies the computation of the static stress, its transmission to the dynamic analysis where the pre-stress has to be included in the analysis. A lot of tests have been performed in order to verify the correctness of the approach.
