Characterization of the viscoelastic behavior of a simplified collagen micro-fibril based on molecular dynamics simulations

- Steered molecular dynamics (SMD) simulations were performed on a simplified collagen micro-fibril.
- A QLV model was used to characterize the creep behavior of cross-link region.
- A delay element was introduced to represent the effect of force wave propagation.
- The force wave propagation is correlated with the theoretical wave speed in rods.
- A reduced model was developed to predict viscoelasticity of collagen micro-fibril.
