Contexte et objectifs
World leader in gases, technologies and services for industry and health, present in 72 countries with scientific expertise in oxygen, nitrogen and hydrogen. Identify and evaluate deformation mechanisms on different materials during mechanical stress.
Deformations measurement undergone by a composite material sample during a tensile test in a liquid nitrogen bath.
Deformations measurement during compression and traction tests on foam cubes and dumbbell specimens.
The objective being the determination of the Poisson's ratio and Young's modulus.
Constraints
- Aggressive environment
- Integration with the existing system (Instron hydraulic machine), perfect data synchronization (force, deformations, crosshead displacement) thanks to real-time data transmission to the Wavematrix control software
- Accuracy in a disturbed environment (light, liquid nitrogen bath, bubbles, etc.)
Solution
FVXY and hardware options (filter, specific lighting, special marking..)
