Iyy, Iyz, Izz
Enter the second moments of area for each beam section. Creo Simulate interprets the entered values with respect to the BSCS. The software also displays the values with respect to the BCPCS when you review beam section properties. These properties describe stiffness in bending about a beam's principal Y and Z axes.
You must enter a positive value for Iyy and Izz.
Iyz can be either positive or negative and must obey the rule:
(Iyz)2 < Iyy Izz
Note that Iyz is zero for beam sections for which the BSCS is the same as the BCPCS.
