Effects of local incompressibility on the rheology of composite biopolymer networks
Anupama Gannavarapu, Sadjad Arzash, Iain Muntz +4
Fibrous networks such as collagen are common in biological systems. Recent theoretical and experimental efforts have shed light on the mechanics of single component networks. Most…
Effective Medium Theory for Mechanical Phase Transitions of Fiber Networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Networks of stiff fibers govern the elasticity of biological structures such as the extracellular matrix of collagen. These networks are known to stiffen nonlinearly under shear or…
Mechanical criticality of fiber networks at a finite temperature
Sadjad Arzash, Anupama Gannavarapu, Fred C. MacKintosh
At zero temperature, spring networks with connectivity below Maxwell's isostatic threshold undergo a mechanical phase transition from a floppy state at small strains to a rigid sta…
