• A flat plate can be considered as the extreme of a continuum of forms • A tall beam in bending is more efficient than a flattened out beam. w w w . a u t o s t e e l . o r g Beams in bending
Beam Geometric Non-linearities • Beam stiffness does not necessarily vary linearly with metal thickness • <strong>The</strong>se non-linearities favor aluminum over steel • In the following plots, 2*t/h is the abscissa, where – t is the material thickness – h is the height between the top and bottom flanges • h = 0 for a flat plate • h = overall height – 2*t for all other forms • <strong>The</strong> ordinate is the beam thickness exponent - λ w w w . a u t o s t e e l . o r g
