Response of Electrorheological Fluid-Filled Laminate Composites to Forced Vibration:

  title={Response of Electrorheological Fluid-Filled Laminate Composites to Forced Vibration:},
  author={Yongkyoo Choi and Stephen W. Smith and H. Conrad},
Laminate composite beams consisting of metal or polystyrene outer strips and an electrorheological (ER) fluid (corn starch in corn oil) filler were constructed and tested using the standard Oberst test for viscoelastic materials. Application of an electric field of 2 kV/mm increased both the frequency of the various resonance modes and the loss factor associated with each. The apparent elastic modulus and loss factor of the composite beam and those of the ER fluid alone were calculated… CONTINUE READING
