We propose a physical model for the nonlinear inelastic mechanics
of sticky biopolymer networks with potential applications to inelastic cell
mechanics. It consists of a minimal extension of the glassy wormlike chain
(Gwlc) model, which has recently been highly successful as a quantitative
mathematical description of the viscoelastic properties of biopolymer networks
and cells. To extend its scope to nonequilibrium situations, where the
thermodynamic state variables may evolve dynamically, the Gwlc is furnished
with an explicit representation of the kinetics of breaking and reforming sticky
bonds. In spite of its simplicity, the model exhibits many experimentally
established nontrivial features such as power-law rheology, stress stiffening,
fluidization and cyclic softening effects.
