The mechanical test laboratory can perform measurements at 300 K and cryogenic temperatures: 77 K (liquid nitrogen) and 4.2 K (liquid helium), for determining mechanical characteristics (modulus of elasticity, elastic limit, breaking load, rupture elongation, and fragility) of metals or composites (synthetic composites or highly anisotropic compounds such as superconductors), and the behavior of complete assemblies under flexion, traction, compression or slippage.
The laboratory has:
? A hydraulic press with a compression capacity of 1600 kN.
? An Instron electromechanical machine with a traction and compression force of 300 kN.
? An Instron electromechanical machine with a traction and compression force of 150 kN.
The last of these machines can be fitted with two cryostats for tests at cryogenic temperatures: one with a traction and flexion capacity of 50 kN and the other with a traction capacity of 80 kN and a compression capacity of 150 kN.
Since 2013, a major test campaign has been conducted to optimize (material, torque, surface preparation) friction on the fastening systems of the JT-60SA tokamak’s Outer Intercoil Structure.
