Criticality enhances the reinforcement of disordered networks by rigid inclusions
Jordan L. Shivers, Jingchen Feng, Fred C. MacKintosh
The mechanical properties of biological materials are spatially heterogeneous. Typical tissues are made up of a spanning fibrous extracellular matrix in which various inclusions, s…
Stress relaxation in F-actin solutions by severing
S. Arzash, P. M. McCall, J. Feng +2
Networks of filamentous actin (F-actin) are important for the mechanics of most animal cells. These cytoskeletal networks are highly dynamic, with a variety of actin-associated pro…
Normal stress anisotropy and marginal stability in athermal elastic networks
Jordan Shivers, Jingchen Feng, Abhinav Sharma +1
Hydrogels of semiflexible biopolymers such as collagen have been shown to contract axially under shear strain, in contrast to the axial dilation observed for most elastic materials…
Nonlinear elasticity of disordered fiber networks
Jingchen Feng, Herbert Levine, Xiaoming Mao +1
Disordered biopolymer gels have striking mechanical properties including strong nonlinearities. In the case of athermal gels (such as collagen-I) the nonlinearity has long been ass…
Alignment and Nonlinear Elasticity in Biopolymer Gels
Jingchen Feng, Herbert Levine, Xiaoming Mao +1
We present a Landau type theory for the non-linear elasticity of biopolymer gels with a part of the order parameter describing induced nematic order of fibers in the gel. We attrib…
