Figure 1. Examples of the shapes of leaves for vanishing g₀, i.e., without the presence of point-like internal forces.

The following values of parameters have been used: q₀ = − 1.0, θ_m(0) = 0, m = 1, 2, …, M, κ_y = 10.0, κ_z = 10.0, g₀ = 0.0. (A) Shapes of the beams which form the leaf structure. (B) Projection of the leaf of (A) on the ξ − η plane.
