Dynamics of Smart Structures


The D-SMART research team conducts research in structural dynamics and vibro-acoustics for applications in vibration control, acoustic control and energy recovery. It has expertise in a wide range of traditional passive or active solutions (viscoelastic materials, single or multiple absorbers, piezoelectric shunts, electroacoustic absorbers, etc.), and uses this experience to develop innovative strategies based on new architectures, on the functionalization of complex phenomena, particularly non-linear ones, or on multiphysics couplings by integrating materials with controllable properties, known as intelligent materials. Its skills and resources enable it to combine methodologies, simulations and experiments, and to integrate uncertainties and lack of knowledge for the purposes of robust design.

Goals and Research Areas

The team's objective is to develop vibratory devices with a behaviour that can be controlled to adapt to the stress environment, in order to move towards self-adapting structures in the future. Several challenges must be met in order to achieve this:

  •  Programming the material using various architectural, damping, absorption or control strategies, so that the devices developed can operate in an environment that includes extreme conditions (various stresses, large thermal gradients, low damping levels, etc.),
  • Develop new numerical and experimental methodologies for these new devices: one challenge is to make the most of the data from simulations and experiments to develop the control strategies necessary for their adaptability or self-adaptability.

The team aims to respond to various societal challenges. It aims to participate in industrial development and innovation by being involved in both fundamental and application research. It contributes to environmental issues by sculpting silent and environmentally friendly structures for the future, and by participating in research related to energy efficiency, energy recovery, clean mobility: lightening, electric propulsion. Finally, it is strongly involved in engineering training and in supporting the training-research link, with the consequent development of teaching activities and strong doctoral supervision.


  • Development of multiphysics models adapted to the different stresses to which a structure will be subjected during its life: mechanical, thermal, magnetic, electrical.
  • Development of new modelling strategies based on data, meta-modelling.
  • Development of new model reduction strategies.
  • Design of characterisation or qualification test benches for acoustics, waves and vibrations.
  • Development of experimental planning and characterisation methods to determine the properties of the structures developed, over wide parametric ranges.
  • Development of tools for experimental validation of multiphysics models.
  • Quantification of direct and inverse uncertainties: screening and sensitivity analysis, robustness analysis, parametric identification.
  •  Optimisation and robust design, local and global approaches.
  • Development of decision support tools.
  •  Design and sizing of vibratory or acoustic control systems, active or passive

Implementing our work

The team is recognised for its ability to address a wide range of issues, from "fundamental" aspects to applications. To this end, it has developed numerous academic and industrial partnerships at the departmental, Institute, national and international levels.

It participates in local projects (EUR/BFC Region), national projects such as FUI or ANR, and European projects. At the international level, it maintains collaborations with several foreign universities: University of Bristol (UK), University of Liverpool (UK), UNESP (BR), UFU (BR), USP (BR), University of Sherbrooke (CA), EPFL (CH), Technion (ISR) etc. She is also strongly involved in training at SupMicroTech-ENSMM, the University of Franche-Comté, and in particular in the Smart Mechanics master's degree of the EIPHI University Research School.

It is involved in several CIFRE theses, with recurrent partnerships with large industrial groups such as ALSTOM, EDF, SAFRAN, STELLANTIS, THALES, etc. and SMEs such as EFFBE-Gamma, MMT, Vibratec, etc.

The team relies heavily on the experimental resources of the AMETISTE platform, on equipment for the mechanical characterisation of materials and structures in a wide range of dimensions and frequencies.
