    In this paper,it is considered that the energy decay estimates of the nonhomoge-neous 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.
