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 44. 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.
