 The Decoupling of Damped Linear Systems in Free or Forced Vibration by Fai Ma, Matthias Morzfeld and Ali Imam

Journal of Sound and Vibration329,3182–3202(2010). Primary title page gives full bylines Fai Ma, Matthias Morzfeld and Ali Imam, with UC Berkeley Mechanical Engineering affiliation. Abstract and Introduction describe nonoscillatory free vibration, forced vibration and a time-varying decoupling transformation accounting for both modal damping and forcing effects.
