Stabilité des systèmes non conservatifs et critère du travail du second ordre
Résumé
Non conservative systems leading to a non symmetric stiffness matrix are known to have paradoxical behaviors like destabilization by adding viscosity. The study of divergence instability of non conservative system under kinematics constraints has been reported recently under one kinematics constraint. We investigate here the case of two constraints, to highlight consequences on divergence instability and to illustrate the results on a three degree of freedom Ziegler system subjected to follower loading under two additional kinematics constraints.
