Design principles for energy dissipation in viscoelastic network metamaterials
Niranjan Sarpangala, Sean Fancher, Prashant K. Purohit +1
Mechanical energy dissipation in networked materials is relevant for applications from vibration isolation to impact protection, yet identifying optimal dissipative architectures i…
Length-scale selection in adaptive transport networks
Sidney Holden, Mia C. Morrell, Geoffrey Vasil +1
Adaptive transport networks in biological and physical systems exhibit hierarchical organization, characteristic channel spacing, and robust scaling relations. Existing adaptive ne…
Unidirectional flow from continuous broken symmetries
Aaron Winn, Justine Parmentier, Eleni Katifori +1
Locally broken symmetries are used across fields to transport matter, particles and information in preferential directions. Beyond local mechanisms, spatially distributed nonlinear…
The Geometry of Contraction-Induced Flows
Aaron Winn, Eleni Katifori
Peristalsis is the driving mechanism behind a broad array of biological and engineered flows. In peristaltic pumping, a wave-like contraction of the tube wall produces local change…
Self-construction and destruction of living transport networks
Chanoknun Sintavanuruk, Yoichiro Mori, Reza Farhadifar +1
Biological transport networks adapt through dynamic interactions between material transport and structural modification during growth and development. In this work, we present a mo…
Hierarchical Loop Stabilization in Periodically Driven Elastic Networks
Purba Chatterjee, Eleni Katifori
Network remodeling, or adaptation, in the presence of periodically driven forcings has hereto remained largely unexplored, despite the fact that a broad class of biological transpo…
An efficient spectral method for the dynamic behavior of truss structures
Sean Fancher, Prashant Purohit, Eleni Katifori
Truss structures at macro-scale are common in a number of engineering applications and are now being increasingly used at the micro-scale to construct metamaterials. In analyzing t…
