Figure 8:

Finite element simulations using the N-ODE material model. Boundary conditions on the undeformed geometry are shown in the first column, deformed geometry in the second column, and contours of ${\sigma }_{xx}$ and ${\sigma }_{yy}$ on the deformed geometry are depicted in the last two columns for (a) uniaxial tension, (b) shearing and stretching, (c) torsional loading scenarios. The material is anisotropic, with the directions of anisotropy depicted as quiver plots in the reference geometries. The red vector field corresponds to the stiffer orientation $v_0$, while the black vector field corresponds to $w_0$.
