Vibration Analysis of Rotating Cambered Helicoidal Turbomachine Blades

A procedure for the vibration analysis of rotating cambered helicoidal blades using curved shell finite element based on Mindlin theory is given. The strain displacement relations of Gol den’veizer are used in the development of a thick doubly curved helicoidal shell element including initial in-plane stress effect. The method is applied to rotating cambered pretwisted blades.Copyright © 1997 by ASME
