An associated model of Coulomb friction based on the real area of contact
Manon Thbaut, Laura De Lorenzis
Coulomb friction is a non-associated law: it contains a threshold that depends on the contact pressure, i.e. a stress that is not conjugate to any internal variable, hence it admit…

Fixing non-positive energies in higher-order homogenization
Manon Thbaut, Basile Audoly, Claire Lestringant
Energy functionals produced by second-order homogenization of periodic elastic structures commonly feature negative gradient moduli. We show that this undesirable property is cause…
