@article{ISI:000471298900004, abstract = {Inspired by experiments on dynamic extensile gels of biofilaments and motors, we propose a model of a network of linear springs with kinetics consisting of growth at a prescribed rate, death after a lifetime drawn from a distribution, and birth at a randomly chosen node. The model captures features such as the build-up of self-stress, that are not easily incorporated into hydrodynamic theories. We study the model numerically and show that our observations can largely be understood through a stochastic effective-medium model. The resulting dynamically extending force-dipole network displays many features of yielded plastic solids, and offers a way to incorporate strongly non-affine effects into theories of active solids. A rather distinctive form for the stress distribution, and a Herschel-Bulkley dependence of stress on activity, are our major predictions.}, author = {Goldstein, Daniel and Ramaswamy, Sriram and Chakraborty, Bulbul}, doi = {10.1039/c9sm00205g}, eissn = {1744-6848}, issn = {1744-683X}, journal = {SOFT MATTER}, month = {MAY 7}, number = {17}, orcid-numbers = {Chakraborty, Bulbul/0000-0002-3589-8207}, pages = {3520-3526}, times-cited = {1}, title = {Stress fluctuations in transient active networks}, unique-id = {ISI:000471298900004}, volume = {15}, year = {2019} }
