Research (Publications)

Fracture (S. Ciliberto, P.-P. Cortet, A. Guarino, O. Ramos, S. Santucci, R. Scorretti, Laboratoire de physique, B. Gabrielle, D. Long, E. Mourglia, L. Odoni, P. Sotta, LPMA CNRS/Rhodia, S. Deschanel, N. Godin, G. Vigier, INSA de Lyon, M. Ciccotti, Université de Montpellier 2)

• Experimental studies:
• slow crack growth (paper sheets, polymer films)
• detection ans localization of microcracks using acoustic emissions (solid foams, martensitic transformation)
• stick-slip instability in adhesive bands
• crack growth in filled elastomers
• fatigue damage in fiber glass reinforced polyamides
• multiple cracking in paper and in granular layers
  
• Modelling rupture as a thermally activated process :
  • analytical predictions (lifetime, slow crack growth dynamics)
  • numerical simulations on a disordered elasticlattice

Multiple light diffusion: Boundary Element Model study of geometrical effects (D. Durian, P.-A. Lemieux)

Granular Materials (R. Behringer, J.-P. Bouchaud, P. Claudin, E. Clément, J. Duran, A. D. Rosato):

• Equilibrium state: stress distributions, history dependence of equilibrium (sandpile, silos)
• Surface instabilities.
• Segregation and convection.
