A general-purpose approach to computer-aided dynamic analysis of a flexible helicopter [PDF]

A general purpose mathematical formulation is described for dynamic analysis of a helicopter consisting of flexible and/or rigid bodies that undergo large translations and rotations. Rigid body and elastic sets of generalized coordinates are used.

Modeshapes recognition using Fourier descriptors: a simple SHM example [PDF]

, 2011
The main objective of this study is to develop an alternative criterion for modeshape classification, as the currently available one, MAC (Modal Assurance Criteria), is only a vector correlation representing modeshape similarities.
