VIPER Winter school
06/02/2017 - 09:00 to 09/02/2017 - 18:00
Call for participants to the first VIPER Winter School
3 Days Lectures on “Dynamic and wave propagation in periodic media”
A Winter School devoted to Dynamics and Wave propagation in periodic structures will take place at Ecole Centrale de Lyon from February 6th up to February 8th.
The aim of this winter school is to present a state of the art of periodic structures design tools. During three days, lectures will be given by world specialists on this field of research. The fundamental basis of periodic media, their interest and limitations will be presented. The winter school is open to audience for Master and PhD students, engineers and researchers interested in numerical modelling in vibroacoustics of periodic media.
To participate or to have more information please contact Mlle Zsoka BORI (European Project Manager – Ecole Centrale de Lyon) at: firstname.lastname@example.org
Participations from both the academia and the industry are welcome.
Maximum number is 50.
Registration fees: 150euros, including coffee breaks, lunchs and course supports.
Full program available on: http://viper.ec-lyon.fr
Deadline for registration : 27th January2017
THE VIPER EUROPEAN PROJECT: VIBRO-ACOUSTICS OF PERIODIC MEDIA
VIPER is a European Joint Doctorate network focused on research in VIbroacoustic of PERiodic media. Structural periodic design is a powerful strategy for lightweight structures achievements while remaining a convenient solution for manufacturing aspects. One of the research targets is the inclusion of vibroacoustic design rules at early stage of products development through the use of periodic media which exhibit proper dynamic filtering effects. In order to understand how periodic concepts can improve the broadband vibroacoustic signatures and performances, the VIPER project will develop and validate tools for the design of global vibroacoustic treatments based on periodic patterns allowing passive control of structural and acoustical paths in layered concepts. Dealing with large scale periodic structural-acoustic concepts involves a multi-scale aspect that needs specific numerical tools. A two scale strategy will be pursued to handle periodicity effects: the meso-scale, related to the cell or the span size, and the macro-scale related to the final structure size. Bridging the cell scale behavior and the vibroacoustic indicators is a challenging issue which will dramatically improve the macro structural design.
As the cell topology and constitutive materials are important data, VIPER will consider the combination of different materials and structural arrangements, in which viscoelastic, poroelastic, auxetic materials will play a major role. Finally, this project will also address the lack of perfect periodicity which can be considered both in view of robustness and design analysis of proposed periodicity based concepts. VIPER has a multi-disciplinary character, coupling expertise from material science, vibration and acoustics as well as applied mathematics. It can offer different applications in transports (aeronautics and space, automobile), energy and civil engineering sectors, where vibroacoustic integrity and comfort can be crucial points.
