In this study, we consider the one-dimensional system of piezoelectric beams
with thermal and magnetic effects in the presence of a nonlinear damping term
and with infinite history acting on the mechanical equation. Under suitable
assumptions on the nonlinear damping term and the kernel, we demonstrate the
existence and uniqueness of the solution applying the semigroup theory more
precisely by Hille-Yosida theorem. And by introducing a suitable Lyapunov
functional and using some properties of convex functions, we show the general
stability for the system which the exponential and polynomial decays are
merely special cases. Furthermore, our results are independent of any
relationship between system parameters.
