|Title:||The role of structure in the nonlinear mechanics of cross-linked semiflexible polymer networks||Authors:||Kurniawan, N.A.
|Issue Date:||14-Feb-2012||Citation:||Kurniawan, N.A., Enemark, S., Rajagopalan, R. (2012-02-14). The role of structure in the nonlinear mechanics of cross-linked semiflexible polymer networks. Journal of Chemical Physics 136 (6) : -. ScholarBank@NUS Repository.||Abstract:||The microstructural basis of the characteristic nonlinear mechanics of biopolymer networks remains unclear. We present a 3D network model of realistic, cross-linked semiflexible fibers to study strain-stiffening and the effect of fiber volume-occupancy. We identify two structural parameters, namely, network connectivity and fiber entanglements, that fully govern the nonlinear response from small to large strains. The results also reveal distinct deformation mechanisms at different length scales and, in particular, the contributions of heterogeneity at short length scales. © 2012 American Institute of Physics.||Source Title:||Journal of Chemical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/74787||ISSN:||00219606|
