Calculating the gaskets min radius of curvature
R= CE/S( inches)
where , R= radius of curvature in inches C= 1/2 the thickness of the material E= modulus of elasticity S= maximum fiber stress of yield stress of the material
Example for Buna-N
C = 2.36 mm/2 E= Elongation/Tensile = 4/2150 (1/psi) S =
