The next annual ELyT Lab Workshop on March 12 to 14, 2012 in France
The 4th ELyT Lab workshop will be held in France from March 12 to 14, 2012, in Presqu'ile de Giens (south east).
ElyT School in Lyon 2011
The third edition of the ELyT School was held from the 4th to the 14th of September 2011 in Lyon with the visit of 30 students (20 PhD and 10 Master students) accompanied by four professors from Tohoku University.
The 3rd ELyT lab workshop
The 3rd ELyT lab workshop, held in Sendai during 3 days from February 22th to 24th 2011 has been a great success, involving about 100 researchers (among them 35 French attendees) and several industrial partners. This confirms the dynamism of our joint laboratory. Program and some presentations can be downloaded here. The website is regularly updated.• Biosciences & Engineering (B), • Durability, Reliability in Energy and Transportation (R), • Nano & Micro Scale Materials & Devices (M), • Flow Dynamics, Heat Transfers and Microfluidics (F), • Tribology (T)
Reliability of components used in energy systems and transportation devices is a key issue for the safety and durability of the applications, especially in nuclear power plants on the one side, and in transportation systems (aircraft, trains, ships and cars) on the other side. It is empirically achieved through design using safety margins in material thickness, appropriate design and shapes and short inspection /replacement times. A very important issue is life extension possibilities, mainly for economic reasons. Moreover the nuclear industry has a real difficulty to find new accepted sites. Yet too large safety margins decrease the energy efficiency in an era of shortage and cost increase. So there is an incentive in assessing and monitoring the component damage in a reliable way. This can be done by designing longer-lasting materials and devices; by monitoring devices so that they can be replaced just in time. Indirectly, this requires the best possible understanding of the damage mechanisms and the way to slow them down, reliable and validated simulation tools which may simulate complex geometries and loading histories in a realistic way but also provide the tool to perform virtual experiments and hence ensure a better safety. Robust and reliable health monitoring devices are also necessary. The theme currently hosts five complementary projects:
o NDE & Mitigation combines original electromagnetic and acoustic non destructive devices for the evaluation of creep damage in both the thermal barrier layer and the bulk Ni-base superalloy operating at high temperature (900°C), which can be of interest for both energy production devices and turbine propellors.
o SPWSS focuses on self-powered and wireless smart systems, for interest in transportation industry. The key issue is the increase of energy harvesting of electroactive systems such as piezoelectric devices, so as to develop light and reliable health monitoring devices.
o UMaSCC deals with stress corrosion in components made of stainless steel and/or nickel-base alloys and aims at increasing the SCC resistance by enhancing the surface properties of the materials. It combines a physico-chemical approach of passive film properties with an experimental approach in high-temperature conditions.
o PolymIrrad (NEW) studies the effect of irradiation on polymer and coating aging that can be a risk in the long-term exploitation of nuclear power plants. It combines experimental irradiation skills with modeling the effect of irradiation on the micromechanical properties of polymers.
o Cold spray (NEW), focuses on the cold spray coating process and its numerical simulation, combining experimental and modeling competences. o French side leader : Joël Courbon, joel.courbon[at]insa-lyon.fr Japanese side leader : Yutaka Watanabe, yutaka[at]rift.mech.tohoku.ac.jp
