Specialists in Numerical Simulation and Test Engineering

The added value of CIMES in the product development phase lies in the systematic comparison of our numerical simulations with physical measurements, performed on modern testing and validation platforms. The involvement of our engineers at all levels of completing these test campaigns allows them to have a global vision, to understand the observed physical phenomena and to explain them.

Our experimental methodology is based on a multi-scale approach, from the characterisation of materials, to real-life testing, and testing subsystems in the laboratory.

Characterisation of materials

essais en laboratoire

We perform mechanical tests on all types of materials. These tests can be performed according to national and international standards (ISO, ASTM, EN) or according to customer requirements. The means at our disposal allow us to characterise the behaviour of materials up to breaking point over a wide range of strain rates and temperatures. We can develop the accurate behaviour models to strengthen our numerical simulations and make them more efficient.

Features :

  • Physicochemical characterisation (μ-tomography, SEM)
  • Traction / static compression machines
  • Endurance / fatigue benches
  • Gleeble 3500 Thermomechanical Simulator
  • Hydraulic cylinder
  • Hopkinson bars

On-site tests

Thanks to its experience, CIMES can offer tailor-made test campaigns, seconded on the site. Real-life tests provide an image of the behaviour of structures in their real environment. We establish protocols adapted to the particular situations, by choosing the acquisition equipment, then supervising the preparations (gluing of gauges, accelerometers, etc.) as well as the progress of the tests. Afterwards, we carry out signal processing, measurement analysis and correlation with digital models.
