Non uniform stability for the Timoshenko beam with tip load
Denis Mercier, Virginie Régnier
In this paper we consider a hybrid elastic model consisting of a Timoshenko beam and a tip load at the free end of the beam. Under the equal speed wave propagation condition, we sh…
Remark on stabilization of second order evolution equations by unbounded dynamic feedbacks and applications
Zainab Abbas, Kais Ammari, Denis Mercier
In this paper we consider second order evolution equations with unbounded dynamic feedbacks. Under a regularity assumption we show that observability properties for the undamped pr…
Boundary feedback stabilization of a chain of serially connected strings
Kais Ammari, Denis Mercier
We consider N strings connected to one another and forming a particular network which is a chain of strings. We study a stabilization problem and precisley we prove that the energy…
Spectral analysis and stabilization of a chain of serially connected Euler-Bernoulli beams and strings
K. Ammari, D. Mercier, V. Régnier +1
We consider Euler-Bernoulli beams and strings alternatively connected to one another and forming a particular network which is a chain beginning with a string. We study two…
Mean position of a particle submitted to a potential barrier
Denis Mercier, Virginie Regnier
A one-dimensional Klein-Gordon problem, which is a physical model for a quantum particle submitted to a potential barrier, is studied numerically : using a variational formulation…
