 Stresses in a clamped circular plate Who can help me out on this one! I have a circular plate which is clamped around its outer edge R and free (not supported) on its inner edge r (the plate has a hole in the center) Over the entire plate there works a uniform distributed or not uniform load. The plate has a R of 75 mm and r of 50 mm and thickness t of 25 mm. We need to use a plastic calculation and not a elastic. Now i wish to calculate the shear and bending forces at the out edge of the plate. Who got any suggestions for this? Suggestions for elastic method are welcome as well. I know roarks gives some example of how to deal with this problem but i do not know if i may use these formulas do to the high thickness of the plate compaired to its inner and outer diameter.
