Aplly distance instead of force

[marshell]

Hello,

I am using Cosmos Professional, and I am trying to apply a distance to a beam, to get the force. Is this possible? I know how far I need to move it, and want to know the force to do it.

I have been applying forces, and adjusting it, until I get the correct displacement, but it would be much easier to just put in my the information from the start, and have what I need come out.

Any help would be greatly appreciated.

Thank You,

Marshall

Yes you can apply a displacement instead of a force. You might need splitlines to give you the right locations for the displacement. The process is the same a applying a force just change the units (IIRC) To get the resulting force you need to then use a menu option.. I forget the heavy details.. Let me check an analysis I did a while ago for the method.

This is called enforced displacement loading.

1. Watch the coordinate system you are using for the X,Y and Z components.
2. If the force direction doesn't match the coordinates you are using, decompose the force vectorially and apply components.
3. The displacements will not follow the deflection. They will always point in the same direction.
