Der volle Inhalt der QuelleThis thesis focuses on the development of a multi-scale model of the hygro-mechanical behaviour and the study of the shape stability of glued laminated timber (GLT) made of Pinus pinaster (Ait.). Wooden structures are subject to dimensional variations due to changes in climatic conditions. In the case of GLT structures, shape stability can be achieved through systematic design based on the properties of the constituent lamellae. To this end, a multi-scale model based on an exhaustive bibliographic study of the properties of Pinus pinaster (Ait.) has been developed. Using a numerical homogenisation method and a metamodel based on Non-Uniform Rational Basis-Spline (NURBS) hypersurfaces, this model provides a spatial representation of the heterogeneous, variable, and anisotropic properties of Pinus pinaster (Ait.) lamellae. In addition, configurations of GLTs, based on laminate theory, have been proposed and experimentally subjected to variations in climatic conditions. The induced displacements are measured using a digital image correlation method. Finally, a comparison of the displacements is carried out, enabling the recommendation of GLT configurations that improve the shape stability of the GLTs produced by the Gascogne Bois company

Der volle Inhalt der QuelleThe carbon fibre composite materials cover a lot of manufacturing industries. To assemble parts of these composites several techniques are used. The technique using electromagnetic induction is very interesting; for his advantages such as the fast, without contact and localised transmission of energy to the assemblage interface. The goal of this thesis is to model in 3D, the induction heating of composite materials by taking into account of the anisotropy. Owing to the problem of the scale factor, these materials are replaced by homogeneous equivalent materials; so their electromagnetic and thermal properties are obtained either by using the homogenisation or experimental methods. In this work, to identifying the electric conductivity, one proposed an experimental method based on the impedance measurement. In addition, in our case, these materials are in the form of plate with very small thickness compared to the other dimensions. The shell elements associated to the nodal finite elements are then used. Two models have been developed, a monolayer anisotropic shell elements model applied to composites of unknown structures and a multi-layer model dedicated to the laminated composites with oriented structures. A confrontation between the simulation and experimental results (in induction heating) gave an acceptable difference. These models are applied to improve an industrial application of an induction assembly of composite materials

Der volle Inhalt der QuelleA fine thermo-chemo-mechanical modeling of the material behavior is necessary in order to predict composite parts final shape and properties. There are two options in order to feed these models: estimating the material effective properties thanks to the properties of its constituents, or directly measuring the composite material properties. At first, a multiphysics model of the thermosetting resins characterization device called PvTα was developed. It was validated compared to experimental results and suggested that temperature and degree of cure gradients had to be taken into account when measuring the resin bulk modulus. Then, asymptotic expansion homogenization method was used to model the heat transfers during the cure of composite materials. The upscaling possibility was discussed. This method was then applied to a linear elasticity model, allowing to estimate thermal expansion and chemical shrinkage tensors, as well as the mechanical properties evolution of a unidirectional material during cure. The coupling of these different physics was performed, leading to the prediction of the deformation of a part during cure. Finally, a new characterization device was developed. It allows for the simultaneous recording of the material deformations along two different directions, as well as the degree of cure and temperature. The first results are very promising and validated compared to other measurements and to numerical results from the homogenization method

Der volle Inhalt der QuelleThe main objective of this work is the full elastic characterization of anisotropic composite materials which are elaborated as thin plates of a few millimeters. The elastic properties are obtained from wave velocity measurements using two devices: an immersion bench with classical piezoelectric transducers, and a contactless device based on a Nd YAG pulsed laser for the generation of ultrasounds and an interferometer probe as a receiver. The immersion technique has appeared very efficient for the determination of anisotropic elastic properties. Thanks to an optimization process; the nine independent elastic constants of orthotropic composite materials have been successfully determined from phase velocity measurements using only one sample. Furthermore, we have developed an original approach based on a statistical method to evaluate the errors on the optimized elastic constants. Because of their possibilities of following the elastic properties of materials versus temperature, we have also been interested in contactless techniques. The preliminary tests have been realized at room temperature in order to evaluate the potentialities of this approach. We have studied the wave propagation in an aluminum matrix composite reinforced with unidirectional carbon fibers. With this technique, because of the point nature of both the acoustic source and the optical probe, only group velocities can be measured. The determination of elastic constants from these velocities is a difficult task, especially when we have no information about transverse modes. So, because it is difficult to measure the velocities of these modes, we have solved this inverse problem with numerical simulated data using a particular optimization process
