Other Calculations

Perform UCS-66 calculations: Selecting this check box will cause the software to perform UCS-66 toughness calculations on the component. This option is only available to materials that are classified as UCS materials per Table UCS-23.

Exemption Drop-down: When UCS-66 calculations will not be performed (the software will not allow these calculations when a non-UCS material is used), an exemption must be entered. The exemption may be typed in or selected from the drop-down options, but the user is responsible for ensuring that the exemption selected is valid for the material, service, etc., in question.

MDMT Reductions

Apply UCS-68(c): Selecting this check box will give an additional flat reduction in the allowed MDMT per UCS-68(c). Carefully review this paragraph as there are steep requirements for this exemption.

MDMT

MDMT Pressure: The net internal pressure (concave side) on the component coincident with the minimum design metal temperature (MDMT). This includes static head.

MDMT Curve: The notes in Figure UCS-66 provide the criteria to assign the MDMT curve to the material and product form of the component. Curve A will give the least favorable allowed MDMT and Curve D will give the most favorable allowed MDMT. When UCS materials do not have a clear match using the criteria, they are assigned a conservative value of A. As the software cannot currently obtain possible improvements in curve rating due to heat treatment and other factors, the user may override the curve value.

 

Dry Weight/Flooded Weight: Currently these values are not calculated in the software. Any input in these fields will be added to the summary page information. These values will also need to be added as attachment weight to be considered in the structural calculations.

Surface Area/Volume: Currently these values are not calculated in the software. Any input in these fields will be added to the summary page information.
