The following features are available with the 2022.2.0.5930 Release of DesignCalcs:
The following updates have been made to the Cone-to-Cylinder Analysis:
The Cone-to-Cylinder Analysis now includes updates to the 2021 Edition of ASME Section VIII, Division 1 Appendices 1-5 and 1-8.
The Cone-to-Cylinder Analysis now allows for different longitudinal efficiency values to be input for the internal pressure and external pressure cases. This allows the user to not have to be overly conservative by picking the lower value.
The Cone-to-Cylinder Analysis now defaults the cylinder longitudinal joint efficiency to 100% for large end junctions under internal pressure to take advantage of language in Appendix 1-5.
The Cone-to-Cylinder Analysis now allows for the designation of external pressure case design temperature for the ring. This allows the user to not force the internal pressure case and the external pressure case to use the higher of the two values for the ring and therefore penalize the design for cases where one condition has a lower temperature.
The Cone-to-Cylinder Analysis now allows the user to have more options when determining the value of A in the line of support calculations. The user may decide to use the natural log based interpolation instead of the straight line interpolation. The user can also decide to determine the value of A for themselves and input it into the software directly.
The user can now also input the distance to the further part of the cone-to-cylinder junction, which reinforces the ring cross-section to check for compliance.
The Cone-to-Cylinder calculations now base the ring limits on the outside dimensions when the junction is not checked for internal pressure.
The Cone-to-Cylinder calculations now run the method even when the value of QS or QL is negative. It then uses the absolute value of this in the subsequent equations. If these values are negative, the case being checked will fail as it is out of the scope for the method; however, this allows the engineer the ability to review the report and make more effective decisions.
The Cone-to-Cylinder calculations now determine two versions of the required areas when a ring is present: ArL (no ring) and ArL for the large end and ArS (no ring) and ArS for the small end. The use of a ring may increase the value of the required area by presenting a value of k greater than 1. The no ring required areas set k to 1 while the others use the calculated k value. To pass the reinforcement check for the small end, one of the following must be true: [ArS (no ring) >= AeS OR [ArS + As >= AeS]. To pass the reinforcement check for the large end, one of the following must be true: [ArL (no ring) >= AeL OR [ArL + As >= AeL].
The Cone-to-Cylinder calculations now allow the user to input a ring centroid distance that exceeds the centroid limit. This may fail the design depending on the necessity of the ring and the scenarios being evaluated, but in either case, this allows the engineer the ability to review the report and make more effective decisions.
