摘要
该文考虑具有局部非线性反馈的非均质Timoshenko梁的能量衰减估计.由非线性算子半群理论得到系统的适定性;应用乘子方法,给出了系统的能量衰减估计.
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.
