1. A vibration damping element for a vibration damping system for a turbine nozzle or blade, the vibration damping element comprising:
a plurality of identical stacked plate members within a body opening in the turbine nozzle or blade, each plate member in surface contact on a respective wide surface of the plate member with a corresponding wide surface of at least one adjacent plate member, the body opening extending radially within the turbine nozzle or blade, the body opening having an inner dimension and each plate member having an outer dimension sized to frictionally engage the inner dimension of the body opening to damp vibration, wherein the outer dimension of each plate member defines a width that is larger than a thickness of the respective plate member and defines the respective wide surfaces of each plate member.
