Pełny tekst źródłaThe objective of the thesis is to address in a theoretical and numerical way the homogenization of periodic architected and composite media with multiphysical behavior, in the context of generalized continua. The manuscript is thus decomposed into two parts that explicitly cover these issues. The first part of the manuscript deals with the homogenization of periodic and quasi-periodic media towards a strain gradient effective continuum. A discrete homogenization method is applied for architected periodic materials, leading to the elaboration of higher order effective properties in the form of analytical expressions depending on the edge length of the unit cell. The use of a strain gradient formulation allows the quantification of the surface effects (edge effects in 2D) of architected materials. Moreover, a quasi-periodic homogenization is developed from a volumetric expression of the energy and relying on the notion of shape derivative to determine the quasi-periodic effective properties based on the periodic domain being transformed. The second part of the manuscript integrates multiphysical aspects in the homogenization approaches towards generalized continua. The theory of piezoelectric and flexoelectric homogenization is elaborated in the context of periodic homogenization, employing a variational formulation in combination with the extended Hill macro-homogeneity condition. This is followed by numerical applications for the homogenization of piezoelectric composites and architected materials as well as wave propagation analysis. Moreover, homogenization towards Cosserat (micropolar) effective continuum is addressed for the magnetoelastic heterogeneous solids

Pełny tekst źródłaIn this work, we investigate about the interaction between electrical fields and dielectric particles in the dielectrophoretic phenomena, in theorical and numerical ways. The long-term application are related to electromanipulation and caracterisation of biological cells. Understanding these phenomena requires a complete modeling of polarization mechanisms governing the field-particle interaction and implements electromechanical and electrokinetic models. After introducing the necessary concepts and phenomena, we address polarization modeling using potential theory and suggest an approach for a numerical determination of polarization coefficients. We show that if the multipolar expansion can be reduced to the first order for the case of a spherical particle immersed in a uniform field, the higher orders are needed for nonspherical particles. We show also how a homogenization process allows the study of multilayered particles configurations using this approach. As part of the electromechanical study of dielectrophoretic phenomena, we implement the multipolar approach for two applications numerically treated. We show the relevance of this approach to calculate the force and torque exerted on a particle in situations where the applied field has strong non-uniformities, where the classical dipole approach turn out to be much less efficient. The particle and the suspending medium are in reality two media in contact but not independent as some electrokinetic phenomena occur at the interface. These interfacial effects are addressed in order to be taken into account in the electrorotation phenomenon of a biological cell. The model dealing with the whole problem of a charged spherical particle immersed in a suspension medium and subjected to a rotating field and taking into account the electroosmotic effects is treated. The resolution of the corresponding coupled problem using the finite element method shows the relevance of this approach

Pełny tekst źródłaThis doctoral dissertation addresses the analysis and the modelling of the large amplitude nonlinear vibrations of thin structures with piezoelectric transduction. This type of system is used in numerous applications, such as Micro-Electromechanical Systems (MEMS), control-based systems or energy harvesting. This work proposes a numerical strategy to compute efficiently the nonlinear dynamics of electromechanical problems with geometric nonlinearities. The methodology is founded on the computation of modal reduced order models obtained from analytical and finite element approaches. In the latter case, the reduced order models are obtained by non-intrusive strategies using existing finite-element codes. Then, they are finally computed with a numerical method of continuation of periodic solutions. Original results are presented, about the validation of the non-intrusive methods and the convergence of the modal reduced order models, for reference thin structures. An experimental strategy is also proposed to highlight nonlinear phenomena on a structure with fully integrated piezoelectric actuation and detection. A phase locked-loop experimental continuation procedure is used to measure exchanges of energy due to internal resonances between asymmetric vibration modes in circular elastic and piezoelectric plates
