TOWARDS FAILURE OF CYTOSKELETAL ACTIN NETWORKS

摘要

A numerical model is presented that describes the shear deformation of networks of cross-linked cytoskeletal actin filaments subject to large strains. Thermal undulations are accounted for in the initial configuration. The results show that at small strains the network deforms by filament bending, while at large strains percolations of straightened-out filaments are formed causing severe strain hardening.
