These complex interactions lead to a new mechanical response with emerging properties, such as palsticity and non linear<br \/>reponses. Using experiments on model systems and simulation, I will explore the mechanical response of such an assembly to an uniaxial compression, and try to link the observed scalings to the micro scale structure of the fiber network.<br \/>In a second part, I will explore the unfolding of poplar tree fruits. These fruits, while quite small (5mm), can release a coton ball of several cm that plays a important role in the transport of the seeds. Looking at the different scales of the fruits, I will<br \/>isolate the key ingredients allowing to unpack fibers assemblies, and try to reproduce it in the lab using active fibers.<\/p>\n<p>\n<\/div><\/div><\/div><\/div><\/div><\/section><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":187,"featured_media":0,"template":"","class_list":["post-21081","event","type-event","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/event\/21081","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/event"}],"about":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/types\/event"}],"author":[{"embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/users\/187"}],"wp:attachment":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/media?parent=21081"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
