Numerical solutions for a Timoshenko-type system with thermoelasticity with second sound

Published 25 Dec 2015 in math.NA | (1512.08006v1)

Abstract: In this work, we consider a nonlinear vibrating Timoshenko system with thermoelasticity with second sound. We recall first the results of well-posdness and regularity and the asymptotic behavior of the energy obtained in \cite{Ayadi}. Then, we use a fourth order finite difference scheme to compute the numerical solutions and thus we show the energy decay in several cases depending on the stability number. R\'esum\'e : Dans ce travail, on consid`ere le syst`eme de Timoshenko non-lin\'eaire avec Thermo-\'elasticit\'e et deuxi`eme son. On rappelle d'abord les r\'esultats d'existence, de r\'egularit\'e et du comportement asymptotique de l'\'energie obtenus dans \cite{Ayadi}. Ensuite, on valide num\'eriquement ces r\'esultats th\'eoriques. Pour cela, on utilise une m\'ethode de diff\'erences finies d'ordre $4$. Ainsi la solution num\'erique obtenue permet de valider la d\'ecroissance de l'\'energie dans plusieurs cas selon la valeur du param`etre de stabilit\'e.
