LMA - Laboratoire de Mécanique et d’Acoustique

Materials and Structures Team

The "Materials and Structures" group is in charge of the research at LMA in the field of solid mechanics. This research concerns fundamental issues as well as applications, such as the problems raised by industry or more generally society. The team develops all kind of possible approaches: experimental, numerical, or theoretical.

Main scientific topics

  • Micromechanics and scale transitions: predictions of thermomechanical properties of composite materials from the knowledge of their microstructure. The same methods are also applied to the prediction of interface constitutive laws from the knowledge of the structure of a thin layer. Optimization of microstructures with respect to a desired given property. Inverse problems and identification.
  • Contact, friction, interfaces: analysis and computing of structural phenomena involving contacts and friction between solids: jamming, squeal, impacts.
  • Multiphysic couplings: modelling of chemio-active continua, molecular adhesion, tribological surface transformations.
  • Structures: vibrations and nonlinear dynamics, bifurcations and continuation methods, structures with uncertainties, thin structures, damage in composite solids, analysis of rubber metal bonded parts.

Transversality within the lab

  • Interactions with the "Sounds" group on the theme "Vibrations and nonlinear dynamics"
  • Interactions with the "Waves and Imagery" group on the themes “Seismic wave propagation and bonding”, “Imaging and high-performance computing” and “Power law-based viscoelasticity”.

Contribution to socio-economical aspects

  • Civil engineering: masonry structures
  • Nuclear energy: analysis of deformations of the nuclear fuel in nuclear power plant, safety of nuclear reactors
  • Aerospace engineering: interaction aircraft tyre/runway, rotors of helicopters, deployment of flexible structures.
  • Railway transport
