fatigue study with screws

Discussion created by 1-9ERK6S on Jun 24, 2009
Dear SolidWorks Simulation group:

I have an assembly with two parts. These two parts are screwed together using two screws. One of the parts is under load.

So, I did a stress analysis with 2 bolts (with torque specified) and the load. The problem is in Fatigue analysis, how do I specify load ration just for the load and keep the bolt torque constant? I believe that, when I specified loading ratio, it applies to all the load, ie, the load + two torque on the bolts.

Any suggestion?
