To understand unique mechanical properties of biomolecules, including their fracture mechanics, a good insight through atomic details is important. In particular, hydrogen bond and disulfide bridge dissociation and reformation play an important role in fracture properties of biomolecules in atomistic scales. This, in effect, would impact on the properties of biomolecules on higher scales. An example of this would be Keratin proteins which are key constituents of ubiquitous biofibers and tissue such as hair, nails and skin layers. In this case, by studying dimer-dimer bonding dissociation and reformation, we can develop a bottom-to-top understanding of the molecular structure of keratin fibers and the fundamental mechanisms of fiber/tissue elasticity, creep, fatigue, fracture and self-healing using molecular modeling and simulation techniques.
