Full textIn the frame of an internal research program called JoSAT (Joint Stress Analysis Tool), SogetiHigh Tech has suggested developing since 2008 a simplified tool for the stress analysis ofadhesively bonded joints. This tool allows for the distribution of both the internal forces anddisplacements in the adherends as well as the adhesive stresses along the overlap to beestimated from specified loads and boundary conditions, and has the advantage of beingextremely time saving compared to conventional Finite Element (FE) analyses.In 2011, this tool was extended to support adhesive material nonlinearities in the form ofspecified adhesive stress-strain evolution laws. However the theory developed wasdemonstrated as valid for the Single-Lap Joint (SLJ) configuration only, and limited to smalllevels of adhesive material nonlinearities. In this context, the objective of the thesis is double. First, extend and validate the simplified tool for the analysis of adhesively bonded joints in the case of nonlinear adhesive as well asadherends stress-strain constitutive behaviors. Then, suggest and develop experimentalprotocols for the characterization of the cohesive properties of thin adhesive layers so that thesimplified tool can be sustained with relevant experimental data in terms of adhesive stressstainconstitutive relationships

Full textThe emergence of composite materials in aeronautics leads to lighter structures. However, these new materials induce new constraints to the assembly process. The adaptation is not yet complete. Indeed many operations are necessary to respect the new requirements, but are considered as non-productive. In the context of the European project LOCOMACHS, an assembly simulation tool is developed to limit the use of these operations. This thesis relates to the validation, from the measure, of the models used for flexible assembly simulation. A method to evaluate the geometry of a flexible component is implemented. The method compensates, by simulation, the effects of the environment on the component during its measurement. A sensitivity analysis of the method against changes in various measurement parameters and simulation parameters is performed in order to define a framework for implementation. Parameters of the model used to perform the compensation by simulation are not representative of the actual behavior. A modal analysis of deviations to a chosen reference geometry contributes to the adjustment of these parameters. This reference geometry is obtained by a reversal method applied in a flexible context to cancel some of the effects of the environment on the measured geometry of the component. The gap between the assembled components is the geometric key characteristic in an assembly of aeronautical composite structure. The assembly simulation, from measuring data of flexible components, enables to evaluate the gap between the components prior to assembly. Gap measurement methods in an assembly of flexible components are proposed, and they have been experimentally performed. The comparison of measured and simulated gaps highlights the performance of the simulation tool, and the difficulties in modeling actual measurement environment and actual assembly environment

Full textThis thesis deals with the development of a mechanical test for the characterization of the practical adhesion of an adhesive to a substrate. The aim is to study the different methods of characterization of the adhesive strength in bonded joints and to model the associated behaviour. The first part of the thesis consists of a bibliographic study of the mechanical tests to characterize this adhesive strength. These tests are classified by distinguishing them in propagation or in initiation of rupture. This state of the art demonstrates the advantage of using the 3-point bending and the butt joint tests for this study. The second part of the thesis presents the different materials and the various surface treatments used to vary the adhesion of adhesives to the substrate. The third part presents the core of this thesis work which is the 3-point bending test. The study shows that this 3-point bending test leads systematically to initiate a localizable adhesive rupture on the surface of the substrate, at least for the adhesives used in our study. An energy approach of the test allows to determine an adhesion criterion independent of the physical parameters of the materials and dimensions of the specimen. On the other hand, it has been shown that the thinner the substrate, the more precise the results of the adhesive strength. Finally, a fourth part is devoted to numerical modelling by the finite element method. The results obtained show that opening constraint in mode I is that which controls the rupture. In conclusion, the 3-point bending test clearly allows to measure the energy of the adhesive rupture initiation

Full textRecent advances in modern construction have led to the systematic use of combined concrete slab and timber beams as a horizontal load bearing structural component, the latter playing an identical role as steel beams in a composite concrete steel floor. Unfortunately the well-established rules governing the design of shear connectors for structural composite concrete-steel floors cannot be applied directly to wood-concrete composite structural elements due to the nature of the bond that exists between wood and connecting elements. Thus the thesis was aimed at investigating the mechanical behavior of two types of shear connector using static tests. They consisted of a dowel-type connector with a metal base plate and a tubular connector. Using a shear test rig preliminary lateral and axial resistance of different nails, screws with and without disc springs as well as punched metal plates were investigated. These were compared with Eurocode 4 recommendations and the observations led to the design and testing of standardized pushout specimens for both connector types according to the provisions of Eurocode 4. Two predictive techniques were developed to account for the serviceability limit state as well as the ultimate resistance of the connectors. For the former, an elastic model was used to predict the load-deformation characteristics of the dowel through an exact stiffness formulation of a beam on elastic foundation. While the ultimate resistance was based on a modified Johansen yield model. Comparisons between the theoretical and experimental results were found to be in good agreement

Full textThe objective of this work is a first step to develop flower-like and hyperbranched polymers by selfassembling and crosslinking of associative triblock copolymers in selective solvents. The second aim is to study structural and dynamic properties of these architectures in solution by light scattering and rheology on a broad range of concentrations. The first part of this work consisted in synthesizing triblock copolymers based on polybutadiene (PB), and poly(ethylene oxide) (PEO) by end-capping them with crosslinkable solvophobic blocks; poly(dimethyl maleimido ethyl acrylate) (PDMIEA) and poly(methacryloyloxyethyl acrylate) (PMEA), respectively. The second part of this work consisted in elaborating flowers-like and hyperbranched polymers (HyperMac) by self-assembling the PAME7-b-PEO270-b-PAME7 copolymer in water, followed by crosslinking the micelles cores in order to freeze the structures. Light scattering revealed that the size of the objects depended on the concentration at which the polymers were crosslinked. Local dynamics and osmotic compressibility were independent of the architecture (star, flower or HyperMac) at high concentrations. In addition, a self-similarity of the structures was observed regardless their types. Rheology measurements showed an increase of viscosity with the size and the branching degree of the architectures. The concentration dependence of the viscosity was the same for star- and flower-like polymer in water
