Indicates the in-plane sustained stress index (Ii) value.

Specify this value for any point in the piping system by selecting the SIFs & Tees check box on the Classic Piping Input dialog box. Type the node number to which the stress index applies. Then, specify the In-Plane (Ii) value on the SIFs/Tees tab.

  • For more information on stress intensification factors (SIFs), see Stress Intensification Factors and Stress Indices Details.

  • For more information on using local coordinate systems to define in-plane and out-plane, see Tee Elements and Stress Intensification Factors (SIFs) in CAESAR II Local Coordinate Definitions.

  • If you do not specify a value in the In-Plane Index (Ii) box, CAESAR II sets the value to the greater value of either 0.75 multiplied by the In-Plane SIF value (ii) or 1.0.
