Comments

  1. 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:(1)
    ( F 1 × T × P A ) ( L 12 + L 34 )
    where PA is the panel surface area (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 x F1 x T).

    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.

  2. Poisson's ratio coupling for extensional effects is ignored.
