Phys. Rev. Lett. 89, 018302 (2002) [4 pages]Dynamics of Folding in Semiflexible FilamentsReceived 7 March 2002; published 14 June 2002 The dynamics of a single semiflexible filament under the action of a compressing force is simulated. We find that the filament folds asymmetrically with a folding length which depends only on the bending stiffness κ and the applied force f. It is shown that this behavior can be attributed to the exponentially falling tension profile in the filament. While the folding time τ0 depends on the initial configuration, the distance moved by the terminal point of the filament and the length of the fold scales as τ1/2 at τ≫τ0 and is independent of the initial configuration. © 2002 The American Physical Society URL:
