Abstrakt EN: Presented paper deals with modelling of a twisted blade with rhombic shroud as one-dimensional continuum by using beam finite elements with linearly varying cross-sectional parameters. The blade is clamped into a rotating rigid disk and the shroud is considered as a rigid body. Besides, in consequence of eigenfrequencies comparison with a 3D finite element model of the identical blade, material properties tuning is performed.
