The DMSM at the Institut Clément Ader

The Institut Clément Ader (UMR CNRS 5312) is the solid mechanics research laboratory of Toulouse and the region; it is under the aegis of the CNRS. The Institute brings together research teams from four institutions and three ministries including l’Université Toulouse III Paul Sabatier (National Education), l’INSA (National education), l’ISAE-SUPAERO (Defence) andl’Ecole des Mines d’Albi (Industry). These organizations are located in three cities in the Midi-Pyrénées region: Toulouse, Albi and Tarbes.

Around 80 researchers and associate researchers organize and coordinate their activities in four Research Groups :

  • MSC: Composite materials and structures
  • SUMO: Surface, Machining, Materials and Tools
  • MS2M: Modelling of Mechanical Systems and Microsystems
  • MICS: Metrology, Identification, Control and Monitoring

Le DMSM is involved in three of the four research groups : MSC, SUMO, and MS2M.

Involvement of the DMSM in the research activities of the MSC

Four professors of the DMSM carry out their research activities within the Composite materials and structures Group (Groupe MSC of the ICA), mainly in the SIMU area, but also in certain areas of the MAPP Group (topics in bold below).

  • Area 1 – Structures, impact, modelling, and machining (S.I.M.U.):
    - Topic 1 : Impact – crash (Christophe Bouvet, Samuel Rivallant)
    - Topic 2 : Modelling of behavior (Frédéric Lachaud, Laurent Michel)
    - Topic 3 : Machining (Frédéric Lachaud)
  • Area 2 – Materials, Properties and Processes (M.A.P.P.):
    - Topic 1 : Simulation of processes
    - Topic 2 : Emerging processes
    - Topic 3 : Tooling
    - Topic 4 : Innovative materials and methods for multi-scale properties

Certain activities related to composites, but also to topics of other research groups affiliated with the laboratory, are also dealt by the teams within the scope of collaborative Transverse Research Axis: Machining of multi-material stack (UMM), and Assembies (ASM) of the Instotut Clément Ader.

The team currently supervises around fifteen doctoral students (PhDs underway) and over 25 theses have been defended over the last ten years related to the following activities :

  • Characterization and identification of damage, viscoelasticity, and viscoplasticity, crack propagation, durability, fatigue and environmental effect (humid aging), tolerance to impact damage
  • Numerical modelling of critical structural zones, of energy absorption mechanisms, and of reaction to complex loads (lightening)
  • Optimization of composite structures, armor shielding, machining of composites.

Involvement of the DMSM in the research activities of the SUMO

Three professors of the DMSM contribute to and together run the research activities of Axis 1 of the SUMO group:

  • Area 1 – Fatigue, wear damage, modelling (F.A.M.E.U):
    - Topic 1 : Analysis of interfacial heat transfer
    - Topic 2 : Tribology and hot and cold wear
    - Topic 3 : Modelling the behavior and life under cyclic thermomechanical stresses
    (Rémy Chieragatti, Anis Hor, Catherine Mabru)
  • Area 2 – Functional Properties and Microstructural relationships of Advanced Materials (P.U.M.A.):
    - Topic 1 : AMecanism of deformation, plasticity & microstructural evolution in relation to macroscopic properties
    - Topic 2 : Thermodynamic modeling and simulation and / or kinetic solid phases
  • Area 3 – Machining and Metal-forming (Usi.M.e.F):
    - Topic 1 : Improved quality of machining

    - Topic 3 : Chain of digital design and serviceability of equipment : Virtual Lab

The team currently supervises 6 doctoral theses in the following activities :

  • Fatigue of parts from prés-des-côtes fabrication processes
  • Multi-scale characterization and modelling of monotone and cyclical behavior

Main means used

  • Experimental : stereo-correlation, microscopy (MO, MEB, EDX), fatigue machine (uniaxial and multiaxial), nano indentation tester,...
  • Digital : ABAQUS, LS-DYNA, NASTRAN, Z-set (Zébulon, Zmat)

The team develops partnerships with academic and industrial organizations, sometimes involving French, European (ANR, FUI…) and regional multipartnerships.

Involvement of the DMSM in the research activities of the MS2M group

Nine professors of the DMSM contribute to and together oversee the Axis 1 and Axis 2 research activities of MS2M:

  • Area 1 – System and microsystem engineering (I.S.M.):
    - Topic ISM1 : Design optimization in multidisciplinary or uncertain environment
    - Topic ISM2 : Microfluidics and mechanical microsystems
    - Topic ISM3 : On-board systems and actuators (Eric Paroissien)
  • Area 2 – Structures under severe loading conditions (Miguel Charlotte, Christine Espinosa, Patrice Longère:
    - Topic ISS1 : Systems and structures dynamics (Yves Gourinat, Guilhem Michon)
    - Topic ISS2 : Structures under severe loading conditions (Miguel Charlotte, Christine Espinosa, Patrice Longère)
    - Topic ISS3 : Computational structural mechanics (Miguel Charlotte, Christine Espinosa, Joseph Morlier, Michel Salaün)

Certain activities in modelling developed as proper research activities in this group, and related to topics of other research groups affiliated with the laboratory, are also dealt within the scope of the cross-disciplinary topics and teams, Multi-material machining (UMM) and Assemblies (ASM) of the Institut Clément Ader.

The team is currently supervising some ten doctoral students and post-doctoral students in the following areas:
