Metallic Materials and Structures
facilities
- Resources for producing materials, consisting of:
- Assembly facilities
- Heat treatment facilities
- Machining test facilities
- Environmental characterization facilities (oxidation and corrosion)
- Physical-chemical and micro-structural characterization facilities:
- Electron-microscope facilities with X analyzers and EBSD (Electron Back Scattering Diffraction)
- Chemical analysis and X-ray facilities
- Mechanical test facilities including creep, traction and fatigue machines
Establishing the Behavior and Damage Laws for metallic and composite materials
Along with the machines specific to the field, the department also has several notable facilities:
- a multi-axial fatigue machine (traction, torsion and internal pressure) with a maximum capacity of 63 kN, 500 Nm and 1,500 bars, for metallic alloys, operating up to 1,150°C
- a traction-torsion machine with a maximum capacity of 200 kN and 10,000 N.m with an enclosure that allows for tests on composite parts up to 1,100°C
For calculations, DMSM uses, amongst other resources, a Linux cluster of 60 dual-processor nodes, mainly AMD Opterons, with 2 or 4 giga-bytes of memory per processor. Two interconnection networks link these machines: a Myrinet low latency fast network for the massively parallel calculations and a traditional gigabit Ethernet network for managing the cluster and calculations that that can tolerate a larger latency. The total amount of temporary memory available for calculations is 4.8 tera-bytes, whilst a 2 tera-byte NAS RAID5 disk server supports the user accounts. Two 32 and 64 bit front end processors control access to the cluster.
