This point data represents the surface in the middle area of a wide beam under pure bending (simulated, see graph). In the transverse direction, the transverse contraction creates a curvature in the opposite direction to the main curvature, resulting in this saddle surface. However, the wider the beam (–> plate) becomes, the flatter this curvature becomes in the middle and only the edges bend upwards.
