The MASMECA Technology Platform

ENSTA Bretagne’s scientific mission is achieved through the implementation of tools that predict ageing in mechanical structures, thereby allowing optimal sizing. This process requires multiscale testing, measurement and observation equipment that covers a wide range of scales from micro- to ministructure.

Structured around 5 technical platforms, the MASMECA (Advanced Experimental Mechanics on Materials and Structures) technology platform links research centers with local socioeconomic and industrial organizations, promoting vigilance and transfer of technology to businesses.

MASMECA provides industrial firms with access to its experimental facilities and skills with the aim of:

  • promoting transfer of technology and techniques;
  • meeting businesses’ testing needs and contributing to innovation;
  • developing partnerships between research centers and socioeconomic and industrial stakeholders;
  • expanding the platform’s resources.

 

The 5 technical platforms:
