Shear-induced phase transition and critical exponents in 3D fiber networks
Sadjad Arzash, Jordan L. Shivers, Fred C. MacKintosh
When subject to applied strain, fiber networks exhibit nonlinear elastic stiffening. Recent theory and experiements have shown that this phenomenon is controlled by an underlying m…
Nonlinear Poisson effect governed by mechanical critical transition
Jordan L. Shivers, Sadjad Arzash, Fred C. MacKintosh
Under extensional strain, fiber networks can exhibit an anomalously large and nonlinear Poisson effect accompanied by a dramatic transverse contraction and volume reduction for app…
Stress-stabilized sub-isostatic fiber networks in a rope-like limit
Sadjad Arzash, Jordan L. Shivers, Albert J. Licup +2
The mechanics of disordered fibrous networks such as those that make up the extracellular matrix are strongly dependent on the local connectivity or coordination number. For biopol…
Scaling theory for mechanical critical behavior in fiber networks
Jordan Shivers, Sadjad Arzash, Abhinav Sharma +1
As a function of connectivity, spring networks exhibit a critical transition between floppy and rigid phases at an isostatic threshold. For connectivity below this threshold, fiber…
