F1 |
Effectiveness factor for extensional stiffness along edges 1-2 and 3-4. See comment 2. (Real > 0.0, Default = 0.0) |

F2 |
Effectiveness factor for extensional stiffness along edges 2-3 and 1-4. See comment 2. (Real > 0.0, Default = 0.0) |
The effective extensional area is defined by means of equivalent rods on the perimeter of the element. If F1 < 1.01, the areas of the rods on edges 1-2 and 3-4 are set equal to (F1 × T × PA)/(L12 + L34), where PA is the panel surface areas - half the vector cross product area of the diagonals - and L12 and L34 are the lengths of sides 1-2 and 3-4. Thus, if F1 = 1.0, the panel is fully effective for extension in the 1-2 direction. If F1 > 1.01, the areas of the rods on edges 1-2 and 3-4 are each set equal to 0.5 × F1 × T.
Extensional Area for Shear Panel
Thus, if F1 = 30, the effective width of skin contributed by the panel to the flanges on edges 1-2 and 3-4 is equal to 15T. The significance of F2 for edges 2-3 and 1-4 is similar.
Poisson's ratio coupling for extensional effects is ignored.
