Molecular motors stiffen non-affine semiflexible polymer networks
Reconstituted filamentous actin networks with myosin motor proteins form active gels, in which motor proteins generate forces that drive the network far from equilibrium. This motor activity can also strongly affect the network elasticity; experiments have shown a dramatic stiffening in in vitro networks with molecular motors. Here we study the effects of motor generated forces on the mechanics of simulated 2D networks of athermal stiff filaments. We show how heterogeneous internal motordoi:10.1039/c0sm01004a fatcat:2yvg6h5bo5evjgsvravi3lkt2e
