    Non-linear contact area, average stress issues

    Glenn J

      Hi everyone,

       

      Having some issues here:

       

      I am displacing a sphere into a flat rubber surface using NL Static simulation. I am trying to determine the vertical reaction force of the rubber surface due to it being displaced. For this, I need to determine the contact area of the two parts when displaced, and just the average vertical stress for that contact area.

       

      I can't get the measuring tool to measure the diameter of the contact area from the deformed shape, and I'm not sure how to determine the average stress of a particular area.

       

      Any help would be appreciated.

       

      Thanks!

      Glenn
