How do distinctive mechanical characteristics relate to structural demands of natural nests? Get your science on as we begin to address these questions through experiments with artificial 'nests', and observations of the construction process.
Western Cuyahoga Audubon Society Speaker Series 2019-2020
Program: “Emergent Mechanics of the Cup Nest and Its 'Mechanical Synthesis”
Presenters: Dr. Hunter King, University of Akron
Date & Time: Tuesday, April 7, 2020 at 7:30 PM

Programs are free and open to the public. Donations are appreciated.
Description: From the perspective of polymer research and biomimicry, the cup nest built by some birds is unusual: it’s cohesive without attractive interactions; it is plastic and soft though its elements are elastic and stiff. Birds building this type of nest appear to embody an instinctive understanding of the emergent mechanics of thin, flexible, and frictional grains, one that is currently lacking in the scientific community. How do birds choose elements in order to tune the mechanical performance in aggregate? How do distinctive mechanical characteristics relate to structural demands of natural nests? Get your science on as we begin to address these questions through experiments with artificial 'nests', and observations of the construction process.
Paper: Mechanics of birds' nests subject of NSF research. Potential for innovations in civil engineering and architecture, transportation and advanced manufacturing.Paper
