Estelle Berthier

Postdoc

Estelle works on the mechanical stability of 2-dimensional disordered lattices with geometry set by the force-chains observed in experimental granular packing. She uses network-science tools and rigidity theory to analyze the failure locations and the behavior of the structures. She also works on testing these predictive tests on the failure of 2-d sheared photoelastic granular packings.

    • Estelle Berthier is a postdoctoral scholar at NC State University. She received her Engineering degree and research Master in Material Sciences from the National Institute of Applied Sciences of Lyon, France in 2012. She received her doctorate in Mechanics in 2015 from the University Pierre and Marie Curie in Paris, France ([Manuscript]) and joined NC State in 2017. Her current research involves force networks in granular materials.
