Calculate Yield Strength of Shutter Screen

Input
Yield Strength per material

Mild Steel = 35000
Stainless Steel = 30000
HSLA = 50000

Screen Type
Outside Diameter of Screen (See Links to Tables Below)  inches mm
Screen Wall Thickness inches mm
Slot length perpendicular to axis   inches mm
   For Ful Flo Shutter Screen, slot length = 2" for diameters 8" or less,and 3" for diameters 10" and larger. 
  For Super Flo Shutter Screen, slot length = 2" for all diameters
Number of circumferential slots (See Links to Tables Below)  /circle
( Ful Flo Shutter Screen data table For Stainless, HSLA, and Copper-Bearing Steels )
(Ful Flo Shutter Screen data table For Mild Steel )
(Super Flo Shutter Screen data table For Stainless, HSLA, and Copper-Bearing Steels )
Result
