| Abstract: | The stabilization of nonhomogeneous Euler Bernoulli Beam with two ends free and locally disctibuted damping is studied. The authors take control as displacement and angle velocity acting on one end and prove the exponential decay of energy of the system by using multiplier technique in frequency domain method. |

| Keywords: | exponentically decay C0 contraction semigroup frequency domain method |
