f] are the friction damping matrix and friction stiffness matrix respectively due to the contact mechanism and friction effects between the rotor and pad.
Friction damping technology has already gathered 30 years of design experience (Szwedowicz, 2010) and can effectively reduce the resonance amplitude of interest by using under-platform dampers or by optimizing the shroud coupling.
The response of turbine blade under the influence of friction damping is studied in different ways by different researchers (Berger and Krousgrill 2002, Cameron and Griffin 1989, 1990, Csaba 1991, Den Hartog 1931, Ferri and Dowell 1988, Griffin 1980, 1990, Hundal 1979, Johansson 1992, Menq et al 1986, 1986, Metherell and Diller 1968, Mindlin et al 1951 and Salinturk et al 2001).
Friction damping is replaced by equivalent viscous damping in model.

Plans for future research include developing alternative mechanisms for deployment; designing lightweight, high-force, power-conserving active-control elements suitable for space structures; delineating and optimizing the structural system's hysteretic, viscous, and friction damping components for the effective reduction of vibration; and developing reliable analytical tools to describe the interaction of structure and actuator.
