Cross-linked networks of stiff filaments exhibit negative normal stress.
Motivated by recent experiments showing that a variety of stiff biopolymer gels exhibit highly unusual negative normal elastic stresses, we simulate networks of elastic rods over a wide range of concentrations and bending stiffness. In all cases, we find that sheared networks develop significant negative normal stresses that coincide with other elastic nonlinearities, including shear stiffening...
متن کاملSelf-organization of keratin intermediate filaments into cross-linked networks
Keratins, the largest subgroup of intermediate filament (IF) proteins, form a network of 10-nm filaments built from type I/II heterodimers in epithelial cells. A major function of keratin IFs is to protect epithelial cells from mechanical stress. Like filamentous actin, keratin IFs must be cross-linked in vitro to achieve the high level of mechanical resilience characteristic of live cells. Ker...
متن کاملViscoelasticity of isotropically cross-linked actin networks.
Despite their importance for the proper function of living cells, the physical properties of cross-linked actin networks remain poorly understood as the occurrence of heterogeneities hamper a quantitative physical description. The isotropic homogeneously cross-linked actin network presented here enables us to quantitatively relate the network response to a single filament model by determining t...
متن کاملRandom networks of cross-linked directed polymers.
We explore the effect of random permanent cross-links on a system of directed polymers confined between two planes with their end points free to slide on them. We treat the cross-links as quenched disorder and we use a semimicroscopic replica field theory to study the structure and elasticity of this system. Upon increasing the cross-link density, we get a continuous gelation transition signale...
متن کاملDeformation of cross-linked semiflexible polymer networks.
Networks of filamentous proteins play a crucial role in cell mechanics. These cytoskeletal networks, together with various cross-linking and other associated proteins largely determine the (visco)elastic response of cells. In this Letter we study a model system of cross-linked, stiff filaments in order to explore the connection between the microstructure under strain and the macroscopic respons...
