Laboratory of Mechanical & Material Engineering (LASMIS)

Mechanics and materials are key factors in the development of future mobility and transportation and in the success of the energy transition. Doubling the life of a component reduces the need for recycling and the impact on the environment by half. Lightening structures by optimizing or improving material performance reduces the energy consumption of transportation. We work to ensure that future mechanical components protect society and natural resources.

In this context, UR/LASMIS (Laboratory of Mechanical & Material Engineering) proposes an ambitious and strong project focused on different issues :
  • Extend the life of components (performance + monitoring)
  • Lighten structures (energy consumption, choice of materials...)
  • Develop high-performance materials (mechanically, thermally, chemically...)
  • Develop materials with low environmental impact (agro-materials)
  • Optimize materials, processes, treatments and structures
To carry out these issues, UR/LASMIS relies on specialized scientific research of international level on :
  • Elaboration and treatment of innovative materials: PVD/CVD coatings, nanocrystallized materials, vegetal fibers composites...
  • Surface treatments and manufacturing processes: shot-peening, SMAT, additive manufacturing...
  • Characterization of components and structures: residual stresses, nanoindentation, use of large facilities (synchrotron, neutron sources)...
  • Multiphysics and multiscale Modeling of materials, manufacturing processes and mechanical components
  • Development of advanced numerical tools and software (Finite Element Method, optimization algorithm, meta-model….)
The LASMIS laboratory is composed of about sixty researchers, including 28 permanent staff and about thirty PhD students. Two colleagues from the EPF engineering school are attached to the LASMIS as "associate researchers”. The staff, offices and experimental platforms of the LASMIS are distributed on two sites located in Troyes (10) and Nogent (52).

Our research is focused on product engineering methods such as understanding the physics and micromechanics of materials, understanding the physics of manufacturing process, developing characterization methods and numerical tools. Our scientific activity is based on the use of different equipment grouped in operational platforms:
  • Nanomat'Meca: multiscale characterization of materials and structures
  • Adhere: coatings and surface treatments
  • Num3D: numerical tools and additive manufacturing
A significant part of these platforms has been funded by:
  • Région Champagne-Ardenne and Région Grand Est
  • Fond Européen de Développement Régional (FEDER)
  • Ministère de l'Enseignement Supérieur et de la Recherche
  • Agence Nationale de la Recherche (ANR)
The support from these institution is gratefully acknowledged.

Examples of these components: aircraft engine blades/disks, medical prostheses, gears, chairlift attachments, nuclear waste containers, etc.

Manufacturing processes include shot-peening, Surface Mechanical Attrition Treatment (SMAT), cold expansion, Additive manufacturing, Physical/Chemical Vapor Deposition.
