Folks,
I have a tube loaded in a static torsion condition. The tube is 1"O.D. by .67" I.D. by 36" long. The tube is fixed at one end and theload applied to the other. First I calculated the Shear Stress byhand based on T = S X Z (where T is the torque applied and Z is thePolar Section modulus). That works out to about 48,000 psi. Cosmossays 86,000 psi (about 1.75 times). I turned on large displacement,but didn't see any change in results. Clearly I have made a mistakesomewhere, but this seems so simple I can't figure out where. Iappreciate any input you guys have.
Also, is there a way to get Cosmos to calculate angulardisplacement for the above torque application? I haven't lookedinto figuring that part out yet, but since I am here I thought Iwould ask.
Thanks,
AaronSolidworksSimulation
