SUMMARY:Soutenance de thèse: Félix Benoist - Petit amphi\, bâtiment Pasc
 al n° 530 - 28 Sep 22 14:30
DESCRIPTION:Complex Materials : Frustrated Self-Assembly and Nonlinear Elas
 ticity\n\npar\n\nFélix Benoist\n\n\nThis thesis is divided into two parts
  with little overlap. The first part deals with the pathological self-asse
 mbly of normally soluble proteins. In a number of cases\, they tend to for
 m "frustrated" aggregates which grow only in one direction. We hereby stud
 y the shape and size of the equilibrium clusters formed by particles with 
 directional interactions. This investigation hopefully leads to a better u
 nderstanding of the underlying mechanism of fiber-formation.\nThe second p
 art focuses on the transmission of internal stresses in complex materials 
 such as biological fiber networks and granular matter. We develop a contin
 uum model of such materials\, which accounts for the measured asymmetry in
  their response to tension versus compression. We show analytically and nu
 merically that this may lead fibrous networks to rectify internal stresses
  towards contraction\, and granular media to rectify towards expansion.\nJ
