Description
In this study, we aim to model a current-actuated piezoelectric smart composite beam that is an elastic structure consisting of perfectly
bonded piezoelectric, elastic and viscoelastic layers, taking into account the magnetic effect included in the modeling through a full set of Maxwell's equations. The new Lagrangian in this case for modeling is given by
\begin{equation}
L=\int_{0}^{T}[K-(P-E+B)+W]dt
\end{equation}
(see \cite{4}), where $K, P, E $ and $B$ denote the kinetic, the potential, the electrical and the magnetic
energies of the beam, respectively, and $W$ is the work done by the external forces.
We are interested in examining the system's well-posedness and stability of the system.
