  abstract = {Numerical predictions of the forced vibration of a disk assembly including
	frictional effects between the shrouds are presented concerning engineering
	needs for the blade design process. Assuming a tuned disk assembly,
	numerical static, free, and then forced vibration analyses of a shrouded
	turbine blade measured in the spin pit are performed systematically.
	For the excitation forces of an air jet evaluated from the fairly
	linear behavior of the experimental blade resonance peaks, the reliability
	of the proposed approach is validated through the very close agreement
	of the computed and measured resonant peaks. These resonant peaks
	demonstrate either a fairly linear behavior or a nonlinear one like
	the jump effect of blade resonance amplitudes, or elastic impacts
	between the shrouds. Also, the damping performance for different
	contact configurations between the shrouds is numerically analyzed.
	These numerical results indicate that the shrouds generate higher
	frictional damping for small angles (0{\^a}30deg) between the circumferential
	direction and the normal vector to the contact surface.},
