Thanks a lot Jason and Bonnie for your responses.I really appreciate these elaborate and clear answers.
To just sum up my understanding on this whole topic:
“Centrifugal and all other inertial forces (gravitational, gyroscopic, Coriolis) are calculated at the center of mass and when there is an offset between mass center and tension center, there is a bending moment associated with it (otherwise not). Similarly all the aerodynamic forces are calculated at aerodynamic center and when there is an offset between aerodynamic and shear center there is a torsion (and a delta bending moment which changes every time with angle of attack) associated with it (considering bending moment: flap wise and edge wise are constant, about the aerodynamic center).
Hence when I apply my loads in FE model at shear center I apparently, neglect the torsion moment and the delta bending moment associated with the offset between aerodynamic center and shear center!”
Please let me know, if my understanding is flawed somewhere? Also, did I miss the link between pitch axis with all these centers?
Thanks as always,
