No, it does not. The results are a function of the geometry. However, the results for allowable external pressure are generally higher than those computed using the typical UG external pressure methods. What happens during the analysis when this option is selected?

No, it does not. The results are a function of the geometry. However, the results for allowable external pressure are generally higher than those computed using the typical UG external pressure methods. What happens during the analysis when this option is selected? The software follows several steps in determining values that are needed during the calculations. One of these steps is to determine the lengths, such as LB1 and LB2.

These are the distances between major lines of support, such as heads, body flanges and conical sections. The software does not distinguish large rings that act as bulkheads, according to paragraph 6.

The first calculations that appear for are in the External Pressure Calculations report, with the calculation of the allowable pressure at the given thickness. After completing this step, the software iterates to determine the required thickness for the given external pressure. If the element is a cylinder, the maximum length between stiffeners is calculated. These results are displayed in the summary at the end of the External Pressure Calculations report.

After completing the external pressure calculations, the software calculates individual stresses for each stress category and summarizes them in the Stress Due to Combined Loads report. The allowable stresses are calculated for the combined loads including external pressure. Unity checks according to 5. The software also compares direct axial, shear and bending stresses to their respective allowables. If any of these are higher than the combined unity check, the maximum value is reported as the Unity Check.

In some cases, the allowables may not be calculated, especially when there is no external pressure or when the load is only tensile. Some elements, such as welded flat heads and flanges, are not applicable and do not have any results. If this is the case, the printed stress value may read "No Calc" or may be blank.

If there any conical transitions in the model, the software calculates the necessity of junction rings and their requirements according to section 4. Cone-to-cylinder junction rings must satisfy inertia requirements from equations and The net area of the junction must be greater than or equal to the result of equation The maximum distance from the cone-cylinder junction is defined in paragraph 4.

The distance is defined as, "The nearest surface of the stiffening ring shall be located with a distance of Tr or 1 in. Because the software handles arbitrary sections, the check value is one inch If the ring is farther than one inch from the junction, it is ignored.
