Supplementary Material Dynamic Results a)b)c)d)e)f)g)

The different cases represent various material property configurations. In Figure 8 we show the temporal evolution of different scenarios (a) to (d) for the initially straight bending rod, and (e) to (f) for the elastic helix. The default parameters of the initially straight bending rod are 0 =0, N = 30, ` =4 .0 In (b), we modify N 2{ 10,20,40,60}. The default parameters of the elastic helix are HR =0 .5 m (helix radius), HH =0 .5 m (helix height), HW =2 .5 (winding number), T =1 .0
