• ​Nomenclature used in spring calculations
• Load in Lbs at a Given Deflection and Flat theoretic formulas
• True Radius Factor Shape of the actual edge has an impact
• Corner Radius Factor A spring does not have square corners
• True Cone Height Factor The flat area at the middle of the spring
• Flattening at Edge Factor The flat area at the edge of the spring

​For an approximate calculation, h - (overall height - t) is acceptable. However, this is not accurate.

In fact, h=(overall height - Y), where Y = Cos Beta*t. For small thickness (under 2mm), this is not significant. With thicker disc springs this becomes a major factor for accurate load and stress calculations. This has not been adequately considered in previous technical literature.​
