Hi there, thanks for taking the time to help.
I'm trying to simulate what happens to a flat steel blade clamped between two steel discs when a "centrifugal load" is applied to it.
I've [badly] sketched out the rotor blade and how it is clamped between the rotor discs.
The only model used in the simulation is the rotor blade. I am trying to simulate the centripetal force on the blade by making face 1 and face 2 fixed geometry. I have added an axis in the correct location and I am using this to define a rotation of the blade of 1200rpm.
Whilst the simulation completes without errors, the highest stress concentration is at the tangent edge (indicated top right) between face 1 and the cylindrical face of the small cut out.
Firstly, does it sound like I am correctly defining the restraints and forces in the simulation?
Secondly, if everything sounds correct, is there any way to get rid of the massive stress concentration along the tangent edge? I have seen figures in excess of the yield stress of the material. I find it hard to accept that the stress in that location would be so high.
Thanks again for your help,
Chris
