| Abstract: | In this paper,it is considered that the energy decay estimates of the nonhomogeneous Timoshenko beam with a local nonlinear feedback.The well-posedness of the system is proved via the nonlinear operator semigroup theory.By virtue of multiplier method,the energy decay estimates of the system is given. |
