Hydro-elastic problems; Rigid body modes; SAMCEF formulation
Abstract :
[en] A frequently asked question is to know if the SAMCEF formulation of hydro-elastic problems allows a correct representation of the rigid body modes. In fact, it is current to analyse the free-free vibrational problem, and some people were surprised to loose rotational rigid body modes. The purpose of the present report is to enlighten this point.
