//Maximum pressure in the vessel Pmax (MPa)
Pmax = 1
//Minimum pressure in the vessel Pmin (MPa)
Pmin = 0
//Seating pressure for the gasket PSeat (MPa)

Sut = 780
//Yield tensile strength of the bolt material Syt (N/mm2)
Syt = 580
//Endurance limit in bending Sdash (N/mm2)

//Fatigue stress concentration factor Kf
Kf = 3
//Inner diameter of the gasket Di (mm)
Di = 300
//Outer diameter of the gasket Do (mm)
Do = 300 + (2 * 50)
