About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.

Context

Inria is the French national research institute for digital science and technology. This research center for scientific excellence is on the frontline of digital transformation in Europe and conducts a world-class research covering a wide range of high-impact scientific disciplines: international and industrial collaborations, ground-breaking research, software development, artificial intelligence (AI) and technological startups (DeepTech) are the DNA of the institute. Inria rank 16th worldwide at the AI Research ranking and is the number one European institute for frontier research in digital sciences.

Assignment

Lightweight structures and functional material architectures are the locus of various vibrational or acoustic phenomena which have to be properly understood, predicted and harnessed in civil and aerospace engineering. Their multi-scale nature raises computational and modeling challenges which are the subject of extensive research within the scientific community.

The ANR-JCJC Archi-Noise project aims to unveil disruptive concepts of architected (i.e., lattice-based) materials for Noise and vibration control. This research project aims to leverage a cutting edge computational framework developed within the group, to design novel metamaterials exhibiting enhance low-frequency noise and vibration mitigation capabilities. The candidate will delve into wave physics, enriched continuum theories, structural dynamics and finite element modelling. The project will cover the following topics:

  • Computational mechanics and finite element methods,
  • Dynamics of waveguides,
  • Acoustics and propagation phenomena in complex lattice structures

The PhD applicant will therefore be hired to conduct high-level scientific research along two workpackages (WPs.1-2) of the project, which involve the conceptualization, derivation and resolution of original theoretical and numerical models describing meso-scale architected meta-structures, in order to understand, explore, design and evaluate these novel materials.
