Rigidity of Epithelial Tissues as a Double Optimization Problem
Sadjad Arzash, Indrajit Tah, Andrea J. Liu +1
How do cells tune emergent properties at the scale of tissues? One class of such emergent behaviors are rigidity transitions, in which a tissue changes from a solid-like to a fluid…
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…
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…
Mechanics of fiber networks under a bulk strain
Sadjad Arzash, Abhinav Sharma, Fred C. MacKintosh
Biopolymer networks are common in biological systems from the cytoskeleton of individual cells to collagen in the extracellular matrix. The mechanics of these systems under applied…
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…
Finite size effects in critical fiber networks
Sadjad Arzash, Jordan L. Shivers, Fred C. MacKintosh
Fibrous networks such as collagen are common in physiological systems. One important function of these networks is to provide mechanical stability for cells and tissues. At physiol…
