Defines the modulus of elasticity. These values should be taken from API-650 Table P-1, reproduced as follows:

Design Temp (deg F)

Modulus (psi)

Thermal Expansion (in/in/deg F)

70

29.5E6

-

200

28.8E6

6.67E-6

300

28.3E6

6.87E-6

400

27.7E6

7.07E-6

500

27.3E6

7.25E-6

The value of elastic modulus is automatically defined by the software when you change the design temperature on the general spreadsheet. You can change this value, if necessary.

If the bottom shell course is specified as Stainless Steel, then the modulus value for Table P-1 is not used. Instead, the modulus value is obtained from Table S-6:

Design Temp (deg F)
