BCAM Seminar Rates of Decay of magnetoelastic waves in a bounded conductive medium
Data: Or, Urr 24 2008
Lekua: LNCC/MCT, Brazil
Hizlariak: Gustavo PERLA
We consider a coupled system of evolution equations modelling the propagation of elastic waves interacting with a magnetic field in a bounded simply connected region of the 3-D space. A nonlinear dissipative mechanism is allow to be effective in an small
subregion of the body.We prove that the total energy decays (locally) uniformly as time approaches infinity. This a joint work with R. Coimbra Charao and J. O.Oliveira.
