Exponential decay of the discrete energy for the wave-wave coupled system
Toni Sayah, Toufic El Arwadi
In this article, a numerical analysis of the asymptotic behavior of the discrete energy associated to a dissipative coupled wave system is conducted. The numerical approximation of…
Energy decay analysis for Porous elastic system with microtemperature : A second spectrum approach
Hamza Zougheib, Toufic El Arwadi, Mohammad El-Hindi
In this work, we analyze porous elastic system with microtemperature from second spectrum viewpoint. Indeed, by using the classical Faedo-Galerkin method combined with the a priori…
Theoretical and numerical study of the decay in a viscoelastic Bresse System
Jamilu Hassan, Salim Messaoudi, Toufic Arwadi +1
In this paper, we consider a one-dimensional finite-memory Bresse system with homogeneous Dirichlet-Neumann-Neumann boundary conditions. We prove some general decay results for the…
Bresse-Timoshenko type systems with thermodiffusion effects: Well-possedness, stability and numerical results
Mohammad Elhindi, Khaled Zennir, Djamel Ouchenane +2
Bresse-Timoshenko beam model with thermal, mass diffusion and theormoelastic effects is studied. We state and prove the well-posedness of problem. The global existence and uniquene…
