Strain-stiffening critical exponents of fiber networks under uniaxial deformation
Atharva Pandit, Fred C. MacKintosh, Abhinav Sharma
Disordered fiber networks exhibit a floppy to rigid mechanical phase transition as a function of connectivity. Sub-isostatically connected networks can undergo this transition via…
Nonlinear Poisson effect in affine semiflexible polymer networks
Jordan L. Shivers, Fred C. MacKintosh
Stretching an elastic material along one axis typically induces contraction along the transverse axes, a phenomenon known as the Poisson effect. From these strains, one can compute…
Strain-driven criticality underlies nonlinear mechanics of fibrous networks
A. Sharma, A. J. Licup, R. Rens +4
Networks with only central force interactions are floppy when their average connectivity is below an isostatic threshold. Although such networks are mechanically unstable, they can…
Porosity governs normals stresses in polymer gels
Henri C. G. de Cagny, Bart E. Vos, Mahsa Vahabi +5
When sheared, most elastic solids such as metals, rubbers and polymer hydrogels dilate in the direction perpendicular to the shear plane. This well-known behaviour known as the Poy…
Elasticity of fibrous networks under axial prestress
Mahsa Vahabi, Abhinav Sharma, Albert James Licup +4
We present theoretical and experimental studies of the elastic response of fibrous networks subjected to uniaxial strain. Uniaxial compression or extension is applied to extracellu…
Strain-controlled criticality governs the nonlinear mechanics of fibre networks
A. Sharma, A. J. Licup, R. Rens +4
Disordered fibrous networks are ubiquitous in nature as major structural components of living cells and tissues. The mechanical stability of networks generally depends on the degre…
Active biopolymer networks generate scale-free but euclidean clusters
M. Sheinman, A. Sharma, J. Alvarado +2
We report analytical and numerical modelling of active elastic networks, motivated by experiments on crosslinked actin networks contracted by myosin motors. Within a broad range of…
Nonlinear effective medium theory of disordered spring networks
M. Sheinman, C. P. Broedersz, F. C. MacKintosh
Disordered soft materials, such as fibrous networks in biological contexts exhibit a nonlinear elastic response. We study such nonlinear behavior with a minimal model for networks…
Molecular motors stiffen non-affine semiflexible polymer networks
C. P. Broedersz, F. C. MacKintosh
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 moto…
