This paper shows that the features of the stress state of shrouded blades are connected with the need to allow for constraint of torsion during static deformatin and vibration of the blades. The authors approximate the cross-section by an element of a thin-walled tube which is sufficiently close in dimensions to the peripheral section of the blade. The magnitude of the stresses in a shrouded blade under the influence of the moment ''M /SUB z/ '' are determined. The results of measurement of the strain in a shrouded blade in the last stage of a powerful steam turbine are presented.
