  abstract = {the vibration amplitudes of bladed disk assemblies can be reduced
	significantly by means of friction damping devices such as shrouds,
	damping wires and interblade Friction dampers. in practice, interblade
	Friction dampers are applied in rotating arrangements with various
	geometries showing curved or flat surfaces like so-called wedge-shaped
	dampers. this paper is focusing on a computation method to predict
	the dynamical behaviour of turbine blades with Friction dampers including
	both, curved and wedge-shaped dampers with hertzian and non-herutian
	contact conditions, respectively. the presented computation method
	uses a 3d contact model to calculate the contact forces, including
	normal and tangential stiffnesses, roughness and microslip effects.
	the relative displacements in the contact area can be expressed by
	means of 6 dof of the blade platforms and 6 rigid body dof of the
	damper including translational and rotational displacements. the
	relative displacement of the Friction damper with respect to the
	adjacent blades can be derived from the contact kinematics of the
	blade-damper-blade system and the equations of motion of the Friction
	damper. thus, the model can be applied to investigate spatial motions
	of the bladed disk assembly including bending and torsional vibrations.
	a comparison of different Friction damper designs with respect to
	an optimal damper geometry and damper mass is presented. the advantages
	and disadvantages of each design will be discussed. experimental
	results are shown to validate the developed computation method.},
