The Material Properties dialog box (shown below) displays property specifications for the selected material. The default values for each material property are taken from the material's corresponding standard and are compiled in the material database.
The properties for each material can be modified, although doing so only changes the properties locally. Changing the material properties does not modify the database.
For a list of the materials and their corresponding standards, see Appendix C - List of Materials.
Material Name
Type the name of the material. The software contains a database of materials taken from various standards.
A list of the available materials and their corresponding standards can be found in Appendix C.
Design Stress [Sd or Sts]
Type the yield stress for the material at the operating temperature.
Hydro Test Stress [St]
Type the allowable stress to use during the hydro test condition.
Minimum Yield Strength
Enter the yield stress, Fy, as a function of temperature.
Minimum Tensile Stress
Type the tensile strength designated in the material specification.
Maximum Allowable Tensile Stress
Type the maximum allowable tensile stress of the material.
Maximum Thickness
Type the thickness limit for which the stresses apply.
Material Grade
Type the grade of the material. This specification is taken from the material's corresponding standard.
Material Group
Type the group of the material. This specification is taken from the material's corresponding standard.
