| Abstract: | Forced vibrations of a mass-spring sys- tem are investigated. The spring is made of vis- coelastic material that obeys the fractional deriva- tive constitutive relation. The steady-state re- sponses to simple harmonic excitations are obtained. The effect of the viscoelastic material coefficient on the amplitude-frequency characteristic is discussed. |
