Simulating a Clamping Force from Set Screws

[ayedurand]

I'm trying to simulate a C-clamp arrangement on a sheet of glass that has set screws as the method for generating the clamping force. What I've done is model a couple of cylinders passing through (sliding) one leg of the C-clamp and put an equivalent compressive force on the back end of the cylinder. The set screws press against a steel plate captured in a nylon shim so I don't have point loads on the glass. 

My issue is that this arrangement doesn't preload the C-clamp at all and any reaction forces are due to a sort of prying action from the glass. My failure mode appears to be high tensile stresses in bending near the end of the C-clamp jaw. This is expected but my design is marginal for the loads in question (including safety factor) and I'm not sure I'm getting the whole picture.

Hey, Just trying to solve a similar simulation in fusion, using Spigots and glass balustrading. Were you able to fix this issue ?
