How to Simulate Tension Using Pull Rods

Hello!

I have a designed a microplate made of silicone to test bio material. The microplate is to experience tension along the x-axis by means of two pull rods that are inserted in the holes shown in the side view. 


I simulated the force as its applied to the front and back faces but I don't believe I'm getting the appropriate data. Any help with how to properly simulate tensile force when its applied through the holes would be greatly appreciated
