Abstract: Abstract An enhanced dynamic model for a rotating pre-twisted blade with arbitrary cross-section is proposed in this study. The coupling effects between stretching, bending, and torsion are considered simultaneously in this model. To derive the… read more here.

Abstract: Abstract A novel dynamic model of a rotating variable-thickness pre-twisted blade with elastic constraints is established by using the shallow shell theory. The effects of Coriolis and centrifugal force due to the rotational motion are… read more here.
