Full textThe interaction between an acoustic ultrasonic bounded beam and a multilayered structure immersed in a fluid has been studied. The structure is composed of two anisotropic elastic layers. When the structure is sound, the real structure shows a bonded finite length crack, localised on this internal interface. The aim of this study is to propose a numerical simulation in order to estimate in what extend the analysis of the ultrasonic beam restored by the structure is able to detect the presence of the crack. The representation of the beam uses plane wave decomposition and requires fast Fourier transforms. Kirchhoff’s approximation is introduced. Then the crack is treated as a passive transducer. Numeral studies are proposed in order to estimate in what circumstances crack could be detected. Lamb wave generation could improve the detection

Full textThe modelling of the elastic macroscopic behaviour of heterogeneous materials with the help of homogenization methods are able to take quantitatively into account some descriptive information of their microstructures. These data are obtained more and more precisely thanks to recent resolution’s progress in microscopic (2D) and tomographic (3D) characterization techniques. From the morphological analysis of the microstructure, access is allowed to the modelling parameters. This is the subject matter of this thesis, either for specifically elaborated multiphase materials (“model materials” in the sense of their controlled morphology) and common-used industrial materials, for which one characterizes their structure at a proper scale and measures their overall elasticity properties by ultrasonic methods. The use of the concepts and methods of mathematical morphology provides s statistical description which is used in order to calculate from the model (bounds and estimates) the associated elastic behaviour. One analyses the relative effects of the microstructural parameters on the obtained results from this two approaches, experimental and theoretical, with the help, in particular, of numerical simulations and alternative homogenisation methods by fast Fourier transform calculation. This study deals with the notions of homogeneity / heterogeneity and isotropy / anisotropy of spatial phase repartition, in the case of 2-phase and multi-phase materials. From these analyses, the different homogenisation methods are questioned their respective limitation are discussed
