Stress Intensification Factor using Ratio of Major to Minor Axis Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stress Intensification Factor = (1/6)*(2+Ratio of Major to Minor Axis^2)
W = (1/6)*(2+k^2)
This formula uses 2 Variables

Variables Used

Stress Intensification Factor - Stress Intensification Factor (SIF) is a multiplier factor on nominal stress for typical bends and intersection components so that the effect of geometry and welding.
Ratio of Major to Minor Axis - Ratio of Major to Minor Axis of an ellipse are diameters (lines through the center) of the ellipse. The major axis is the longest diameter and the minor axis is the shortest.

STEP 1: Convert Input(s) to Base Unit

Ratio of Major to Minor Axis: 15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W = (1/6)*(2+k^2) --> (1/6)*(2+15^2)

Evaluating ... ...

W = 37.8333333333333

Depth of Torispherical Head

Go Height of Formed Head = Outer Crown Radius of Head-(((Outer Crown Radius of Head)-(Outer Shell Diameter/2))*((Outer Crown Radius of Head)+(Outer Shell Diameter/2)-(2*Outer Knuckle Radius of Head)))^0.5

Thickness of Shallow dished and Standard dished (Torishperical) Head

Go Thickess of Torishperical Head = (Internal Design Pressure*Crown Radius*(1/4*(3+(Crown Radius/Knuckle Radius)^0.5)))/(2*Design Stress*Joint Efficiency)

Thickness of Elliptical Head

Go Thickness of Elliptical Head = (Internal Design Pressure*Major Axis of Ellipse*Stress Intensification Factor)/(2*Design Stress*Joint Efficiency)

Thickness of Flat Plate Cover or Head

Go Thickness of Flat Plate Head = (Edge Fixity Constant*Diameter of Plate)*((Internal Design Pressure/Design Stress)^0.5)

Stress Intensification Factor using Ratio of Major to Minor Axis

Go Stress Intensification Factor = (1/6)*(2+Ratio of Major to Minor Axis^2)

Depth of Hemispherical Head

Go Height of Formed Head = Outer Shell Diameter/2

Depth of Elliptical Head

Go Height of Formed Head = Outer Shell Diameter/4

Stress Intensification Factor using Ratio of Major to Minor Axis Formula

Stress Intensification Factor = (1/6)*(2+Ratio of Major to Minor Axis^2)
