Dear Nils, my coworker Marcel Clappier has just modelled a 3-D laminated rotor.Our dominant interest was inpredicting the damping behaviour by microslip in the Interfaces.

The result has been published at the ISVR Conference of Malcolm Crocker at Athens recently. Best regards. Lothar Gaul

Oguzhan Yalcin

Dear Nils,

My suggestion to take a look at the website below. I hope that you can find what you want there.

Best Regards...

Nils Wagner

Dear Oguzhan,

Thank you for your answer. I am aware of Grabcad. However, I am looking for a model similar to the one used by Gao et. al. (i.e. Fig. 6) in

Effects of bending moments and pretightening forces on on the flexural stiffness of contact interfaces in rod-fastened rotors, Journal of Engineering for Gas Turbines and Power, Vol. 134 (2012).

Best regards,

Nils
