JHardy, Fhashemi,
Thanks your all words,I'll try do something like you said for a while
And I want to express my question more clearly once again
So first discussing pure torque in real life.
Actually, Pure torque divides into two sorts, one is free torsion which means there isn’t any stress along the axis, so there only is shear stress in the shaft. This is the most simplest pure torque situation such as someone twists a shaft on two end by the two hands with the same force,only twist no press or other force.
I want to simulate this case in Pro/M using 3D model not beam..
If only applying moment force(torsion) at two end of a shaft, no constraints, just like real life, Pro/M warns me ‘no constraint sets have been defined’
If applying moment force(torsion) at one end and constrain at another end,I think the most important thing is how to define this constraint. I tried several methods, but all effort was failed. Sometimes the result wasn’t the situation of real life like my thought or sometimes Pro/M didn’t let me go on. I’ve never got a result it look like in real life.
And other sort of pure torque is ‘constraint torsion’ which means there is stress along the axis even only applying torque, such as one end has been fixed somewhere, then a torque is applied to other end. In this case stress along the axis will be very big if the section of shaft is other shape except circle, square or ellipse. And just because poission’s effect the fixed end will be expand or contract at boundary. I want to simulate this situation too, and I faced more difficult and more fail.
So I really want to know how can I do.
Thanks you all again
