The bilinear elastoplastic model
In the same line of modeling different materials, the bilinear elastoplastic model was added
as an extra option. This model is applied only to angular deformations (bending and torsion)
and includes two linear regimes with different stiffnesses, as shown in Figure 7. The transition
between the elastic and elastoplastic regimes occurs at a limiting angle, given by the user.

Video 2 below shows how the fiber bends differently before and after reaching this limiting angle.
