Plate Roller Capacity Calculation

[natebott]

I have a table listing the capacities of a plate roller for different plate thicknesses and lengths. I was wondering if there is an equation that I can use to calculate capacity for plate thicknesses that are not on the chart. Any help is greatly appreciated.

I would expect it to be related to the
diameter squared of the rollers.

As an approximation, you should be able to figure the plastic bending moment in one of the sections listed, and use that same plastic bending moment as a maximum elsewhere.
