Mission confiée

This PhD opportunity offers to join an Inria Exploratory Action, bridging fundamental research and technological applications for metamaterial design. Working alongside a team of full-time research scientists, you will push the current knowledge on fluid mechanics and metamaterials to unveil next-generation seismic protection systems.

Metamaterials are engineered structures with properties unattainable in natural materials. Using intricate sub-wavelength designs, they have advanced wave control, energy efficiency, and other fields. Acoustic meta-materials, in particular, are promising for sound attenuation, vibration control, and noise-cancellation technologies. Earthquakes, caused by plate tectonics, generate destructive surface waves that threaten infrastructure. Civil engineers have traditionally mitigated these effects with mechanical oscillators and energy-dissipation systems, adapting solutions to the power of earthquakes and the characteristics of vulnerable structures. Another critical challenge is sloshing in liquid tanks, where fluid dynamics at the free surface can cause severe structural damage. Preventing this non-linear phenomenon remains a significant obstacle.

Seismic metamaterials hold great promise for shielding structures from earthquake waves, enabling next-generation civil engineering solutions. A key focus of this project is the exploration of multi-physical coupling phenomena, where interactions between physical domains (e.g., acoustic, elastic, thermal, and fluidic) unveil unique behaviors. Non-linearities, locally resonant mechanisms, and fluid-structure interactions allow the development of highly tunable metamaterials. By examining the interplay of band-gaps, non-linearity, and multi-physical coupling, the project aims to establish a versatile design framework for wave manipulation, noise control, and seismic protection.

Principales activités

Ideal profiles are those with backgrounds in computational mechanics and/or advanced scientific computing.

Candidates should have earned a MSc or equivalent degree in physics (ex. fluid mechanics, acoustics, multi-phase, interactions), applied math (statistics, probability), computational mechanics (structural dynamics, Finite Elements, waves), or in a related field.
