    Exponential decay and numerical solution of nonlinear Bresse-Timoshenko system with second sound
    (Journal of Thermal Stresses, 2022) Salim Adjemi; Ahmed Berkane; Salah Zitouni; Tahar Bechouat
    This paper aims to study the one-dimensional nonlinear Bresse-Timoshenko system with second sound where the heat conduction given by Cattaneo’s law is effective in the second equation. We prove that the system is exponentially stable by using the energy method that requires constructing a suitable Lyapunov functional through exploiting the multipliers method. Furthermore, the result does not depend on any condition on the coefficients of the system. Finally, we validate our theoretical result by performing some numerical approximations based on the standard finite elements method, by using the backward Euler scheme for the temporal and spatial discretization.
