Full textTo solve wave equations in heterogeneous media with finite elements with a reasonable numerical cost, we couple the Discontinuous Galerkin method (DGm) with Spectral Elements method (SEm). We use hybrid meshes composed of tetrahedra and structured hexahedra. The coupling is carried out starting from a mixed-primal DG formulation applied on a hybrid mesh composed of a hexahedral macro-element and a sub-mesh composed of tetrahedra. The SEm is applied in the macro-element paved with structured hexahedrons and the coupling is ensured by the DGm numerical fluxes applied on the internal faces of the macro-element common with the tetrahedral mesh. The stability of the coupled method is demonstrated when time integration is performed with a Leap-Frog scheme. The performance of the coupled method is studied numerically and it is shown that the coupling reduces numerical costs while keeping a high level of accuracy. It is also shown that the coupled formulation can stabilize the DGm applied in areas that include Perfectly Matched Layers

Full textThis thesis investigates defect detection and localization within waveguide assemblies, exploring the interaction between waves in straight waveguides with curved joints and defects. For this purpose, the Wave Finite Element (WFE) method is used. Numerical experiments validate the robustness and accuracy of the WFE method through comparisons with analytical and Finite Element solutions, particularly focusing on dispersion curves and forced responses. Extending the investigation to assemblies with coupling elements, such as joints and defects, the study highlights the efficiency of the WFE method in scenarios involving waveguides.A novel strategy is proposed within the scattering matrix formalism for defect localization, with a specific emphasis on structures containing curved joints. The approach relies on computing the time of flight of narrow wavepackets transmitted or reflected at a coupling element. The strategy is validated through numerical simulations, showcasing precision in defect localization for diverse scenarios, including 2D plane-stress beams and pipes, with a curved joint and a defect.Elasto-acoustic structures are also treated. A reduction strategy based on Craig-Brampton reduction with enrichment vectors is proposed for computational efficiency to model coupling elements. Analysis of power transmission and reflection of waves in structures with defects and joints highlights the significance of the torsional mode in guided wave-based non-destructive testing in this type of system.This research work contributes not only to the understanding of wave propagation in waveguide assemblies but also offers practical strategies for accurate defect detection and localization, with potential applications in diverse engineering contexts

Full textThe main objective of this work is the design of an efficient numerical strategy to solve the Helmholtz equation in highly heterogeneous media. We propose a methodology based on coarse meshes and high order polynomials together with a special quadrature scheme to take into account fine scale heterogeneities. The idea behind this choice is that high order polynomials are known to be robust with respect to the pollution effect and therefore, efficient to solve wave problems in homogeneous media. In this work, we are able to extend so-called "asymptotic error-estimate" derived for problems homogeneous media to the case of heterogeneous media. These results are of particular interest because they show that high order polynomials bring more robustness with respect to the pollution effect even if the solution is not regular, because of the fine scale heterogeneities. We propose special quadrature schemes to take int account fine scale heterogeneities. These schemes can also be seen as an approximation of the medium parameters. If we denote by h the finite-element mesh step and by e the approximation level of the medium parameters, we are able to show a convergence theorem which is explicit in terms of h, e and f, where f is the frequency. The main theoretical results are further validated through numerical experiments. 2D and 3D geophysica benchmarks have been considered. First, these experiments confirm that high-order finite-elements are more efficient to approximate the solution if they are coupled with our multiscale strategy. This is in agreement with our results about the pollution effect. Furthermore, we have carried out benchmarks in terms of computational time and memory requirements for 3D problems. We conclude that our multiscale methodology is able to greatly reduce the computational burden compared to the standard finite-element method

Full textThe guided acoustical propagation is investigated in this work. The propagation of the acoustic waves in a main direction is privileged. A Wave Finite Element method is therefore exploited to extract the wavenumbers. Rigid duct's mode shapes are moreover obtained. For ducts with impedance discontinuities, the scattering matrix can be then calculated through a Finite Element modelling of the lined part. A three dimensional modelling of the lined ducts allows a study of the propagation for the full modes orders, their scattering and the acoustic behaviour of the absorbing materials. The forced responses of various configurations of waveguides with imposed boundary conditions are also calculated. The study is finally extended to the acoustical propagation within waveguides with a uniform mean flow

Full textIn this work, we have introduced the underlying concept of PUFEM and the basic formulation related to the Helmholtz equation in a bounded domain. The plane wave enrichment process of PUFEM variables was shown and explained in detail. The main idea is to include a priori knowledge about the local behavior of the solution into the finite element space by using a set of wave functions that are solutions to the partial differential equations. In this study, the use of plane waves propagating in various directions was favored as it leads to efficient computing algorithms. In addition, we showed that the number of plane wave directions depends on the size of the PUFEM element and the wave frequency both in 2D and 3D. The selection approaches for these plane waves were also illustrated. For 3D problems, we have investigated two distribution schemes of plane wave directions which are the discretized cube method and the Coulomb force method. It has been shown that the latter allows to get uniformly spaced wave directions and enables us to acquire an arbitrary number of plane waves attached to each node of the PUFEM element, making the method more flexible.In Chapter 3, we investigated the numerical simulation of propagating waves in two dimensions using PUFEM. The main priority of this chapter is to come up with an Exact Integration Scheme (EIS), resulting in a fast integration algorithm for computing system coefficient matrices with high accuracy. The 2D PUFEM element was then employed to solve an acoustic transmission problem involving porous materials. Results have been verified and validated through the comparison with analytical solutions. Comparisons between the Exact Integration Scheme (EIS) and Gaussian quadrature showed the substantial gain offered by the EIS in terms of CPU time.A 3D Exact Integration Scheme was presented in Chapter 4, in order to accelerate and compute accurately (up to machine precision) of highly oscillatory integrals arising from the PUFEM matrix coefficients associated with the 3D Helmholtz equation. Through convergence tests, a criteria for selecting the number of plane waves was proposed. It was shown that this number only grows quadratically with the frequency thus giving rise to a drastic reduction in the total number of degrees of freedoms in comparison to classical FEM. The method has been verified for two numerical examples. In both cases, the method is shown to converge to the exact solution. For the cavity problem with a monopole source located inside, we tested two numerical models to assess their relative performance. In this scenario where the exact solution is singular, the number of wave directions has to be chosen sufficiently high to ensure that results have converged. In the last Chapter, we have investigated the numerical performances of the PUFEM for solving 3D interior sound fields and wave transmission problems in which absorbing materials are present. For the specific case of a locally reacting material modeled by a surface impedance. A numerical error estimation criteria is proposed by simply considering a purely imaginary impedance which is known to produce real-valued solutions. Based on this error estimate, it has been shown that the PUFEM can achieve accurate solutions while maintaining a very low computational cost, and only around 2 degrees of freedom per wavelength were found to be sufficient. We also extended the PUFEM for solving wave transmission problems between the air and a porous material modeled as an equivalent homogeneous fluid. A simple 1D problem was tested (standing wave tube) and the PUFEM solutions were found to be around 1% error which is sufficient for engineering purposes
Scala, Ilaria. "Caractérisation d’interphase par des méthodes ultrasonores : applicationaux tissus péri-prothétiques." Thesis, Paris Est, 2018. http://www.theses.fr/2018PESC1107/document.
Full textThis thesis focus on the ultrasonic characterization of bone-implant interphase. This region is a transition zone where the osteointegration process (i.e. the healing process of the tissues surrounding the implant) takes place. Thus, this interphase is of crucial importance in the long-term anchorage of the implant, since it depends on the quantity and quality of the surrounding bone tissue. However, other than being a complex medium in constant remodeling, the newly formed bone presents a multiscale and time evolving nature. All these reasons make the characterization of the bone-implant interphase critical and difficult. In this context, ultrasound methods are nowadays widely used in the clinic field because of their ability to give information about the biomechanical properties of bone tissue. On this basis, with the aim of characterizing the mechanical and microstructural properties of the bone-implant interphase by ultrasound methods, it is important to develop and validate mechanical models and signal processing methods. Due to the complexity of the problem, in order to precisely describe the bone tissue surrounding the implant, first an accurate modelling of bone tissue is essential. Thus, the interaction between an ultrasonic wave and bone tissue has been investigated by also taking into account the effects dues to the microstructure. To do this, a generalized continuum modelling has been used. In this context, a transmission/reflection test performed on a poroelastic sample dipped in a fluid enhanced the reliability of the model. The reflected and transmitted pressure fields result to be affected by the microstructure parameters and the results coming from the dispersion analysis are in agreement with those observed in experiments for poroelastic specimens. Then, the problem has been complicated by considering the interphase taking place between the bone and the implant. In this way, we could handle the complexity added by the presence of the newly formed tissue. As already said, the fact that this interphase is a heterogeneous medium, a mixture of both solid and fluid phases whose properties evolve with time is an additional difficulty. Thus, in order to model the interaction of ultrasonic waves with this interphase, a thin layer with elastic and inertial properties has been considered in the model. The effects on the reflection properties of a transition between a homogeneous and a microstructured continuum have been investigated.Therefore, the characterization of the medium also via advanced signal processing techniques is investigated. In particular, the dynamic response due to the ultrasonic excitation of the bone-implant system is analyzed through the multifractal approach. A first analysis based on the wavelet coefficients pointed out a multifractal signature for the signals from both simulations and experiences. Then, a sensitivity study has also shown that the variation of parameters such as central frequency and trabecular bone density does not lead to a change in the response. The originality lies in the fact that it is one of the early efforts to exploit the multifractal approach in the ultrasonic propagation inside a heterogeneous medium

Full textStructural dynamics can be described in terms of structural modes as well as elastic wave motions. The mode-based methods are widely applied in mechanical engineering and numerous model order reduction (MOR) techniques have been developed. When it comes to the study of periodic structures, wave description is mostly adopted where periodicity is fully exploited based on the Bloch theory. For complex periodic structures, several MOR techniques conducted on wave basis have been proposed in the literature. In this work, a wave and modal coupled approach is developed to study the wave propagation in periodic structures. The approach begins with the modal description of a unit cell (mesoscopic scale) using Component Mode Synthesis (CMS). Subsequently, the wave-based method -Wave Finite Element Method (WFEM) is applied to the structure (macroscopic scale). The method is referred as “CWFEM” for Condensed Wave Finite Element Method. It combines the advantages of CMS and WFEM. CMS enables to analyse the local behaviour of the unit cell using a reduced modal basis. On the other hand, WFEM exploits fully the periodic propriety of the structure and extracts directly the propagation parameters. Thus the analysis of the wave propagation in the macroscopic scale waveguides can be carried out considering the mesoscopic scale behaviour. The effectiveness of CWFEM is illustrated via several one-dimensional (1D) periodic structures and two-dimensional (2D) periodic structures. The criterion of the optimal reduction to ensure the convergence is discussed. Typical wave propagation characteristics in periodic structures are identified, such as pass bands, stop bands, wave beaming effects, dispersion relation, band structure and slowness surfaces...Their proprieties can be applied as vibroacoustics barriers, wave filters. CWFEM is subsequently applied to study wave propagation characteristics in perforated plates and stiffened plate. A homogenization method to find the equivalent model of perforated plate is proposed. The high frequency behaviours such as wave beaming effect are also predicted by CWFEM. Three plate models with different perforations are studied. Experimental validation is conducted on two plates. For the stiffened plate, the influence of internal modes on propagation is discussed. The modal density in the mid- and high- frequency range is estimated for a finite stiffened plate, where good correlation is obtained compared to the mode count from modal analysis
