Our trainingsThe LTDS contributes to the training of the affiliated schools' students. The main activity of the laboratory remains applied research, but we also carry out basic research and we train high level students for research. We are affiliated to the following postgraduate schools: MEGA (Mechanics, energetics, civil and acoustic engineering), EDML (Materials Science) and the Saint-Étienne doctoral school.The LTDS provides permanent training for industrial engineers and researchers in the following domains:

ʈ Tribology.ʈ Worn parts expert reports.ʈ Lubricants.ʈ Surface topography.

ʈ Atomic force microscopy.ʈ Fretting.ʈ Modal analysis.

ʈ Specific tribometers: analytic under ultra-high-vacuum, elastohydrodynamic, molecular, vibro-impact...ʈ Electronic microscopes (TEM, SEM) and atomic force microscopes (electrical and mechanical modes).ʈ Spectroscopy methods: XPS, AES, EELS, X-ray diffraction...

ʈ Multi-scale and 3D roughness measurement (tactile and optical).ʈ Nano-indentators (temperature and dynamic modes).ʈ Field measurements and imaging.ʈ Vibration and multi-load fretting fatigue test rigs.ʈ Seismic platforms.ʈ Motorizations in dynamics of rotating machines.

Our experimental equipments are grouped into six platforms: advanced tribological measurements, dynamics of rotating machines, contact fatigue, high performance processes, skin bioengineering, surface and materials characterization.

Our environment The LTDS is situated in Lyon and in Saint-Étienne. The main facilities are hosted on the premises of the Ecole Centrale de Lyon, and the secondary hosts are the Ecole Nationale d'Ingénieurs de Saint-Étienne and the Ecole Nationale Supérieure des Mines de Saint-Étienne.Our lines of business

The École Centrale de Lyon and the École Nationale d’Ingénieurs de Saint-Étienne are members of the University of Lyon.

From the infinitelysmall

to human-sized objects

Our toolsThe LTDS develops and uses experimental devices and tools for simulations and modelling such as:


Our domainsThe LTDS carries out research in the following domains:

ʈ Tribology: science of friction, lubrication, wear and adhesion.ʈ System dynamics: science of vibrations, system and mechanical devices stability.ʈ Mechanics of heterogeneous solid media: calculations of structure, elements and transformation processes.

We build knowledge and assemble

ours skills to form the future







Our involvement The LTDS deals with technical and economical issues, for instance in the domains of transports, energy or storage of information.We understand, explain, innovate and develop our knowledge and skills in order to:

ʈ Develop the knowledge and understanding of fundamental mechanisms.ʈ Respond to technological issues, anticipate evolutions and support industrial development.ʈ Answer to the society's expectations and questions.

The LTDS contributes to the development of interface science.We therefore include humanities and social sciences as research themes.

Our themesThe LTDS is organized into three research teams working in specific domains. They work on several themes among the following:

ʈ Friction and wear control.ʈ Contact dynamics.ʈ Electrical phenomena at interfaces.ʈ Mechanics of living tissue and biotribology.ʈ Roughness sound and sensoriality.ʈ Modeling and optimization of transformation processes.ʈ Mechanics of granular media and geomaterials.ʈ Durability of assemblies and composite structures.ʈ Active control of multifunctional materials.ʈ Dynamics of uncertain and complex structures.ʈ Robust conception in vibroacoustics.

Our scientific anchorsThe LTDS brings together a community of researchers, teachers, engineers, technicians and administrative assistants.By carrying out experiments and creating models we have a major part in research, teaching of engineering-science and technologies of the future.The LTDS is under the management of the CNRS and three Engineering Schools and therefore our scientific anchors are characterized by:

ʈ A multidisciplinary research, mainly in solid mechanics, chemistry and physics of the materials.ʈ The development of leading edge experiments associated with advanced numerical and phenomenological models.ʈ A constant openness to the scientific community and the social-economic world.
