Fig. 3. (A) Force-displacement relationship of an elastic rod for L=100 µm, R=2 µm, and E=2 GPa. As {varphi} increases, the behavior transitions from cantilever bending to column buckling. (B) Normal force-displacement relationship of the full elastica model (black) and small-deflection, linearized approximation (gray) under differing shear loads for an elastic rod with L=100 µm, R=2 µm, E=2 GPa, {varphi}=45°, and µ=0.25.
