Повний текст джерелаAdditive manufacturing is rapidly expanding and attracting increasing interest from industry, scientific research and the general public. Additive processes have opened up opportunities for producing structures with complex geometries compared to traditional manufacturing. However, the mechanical behavior of additive fabrications under loading conditions is not extensively explored. In particular, the mechanical characterization of these fabrications remains a challenge and often limits itself to pseudo-static investigation fields through conventional mechanical testing methods such as tensile tests. This doctoral thesis aims to contribute to the dynamic mechanical characterization of additive manufacturing on a comparative scale with subtractive manufacturing. This contribution is based on the use of modal methods in response to 'Low Velocity' stimuli applied by an impact hammer, and on a 'High Velocity' dynamic method studying the impact behavior of plates produced by additive (SLM) and subtractive processes

Повний текст джерелаThe additive manufacturing is a field on the rise. However, companies wonder about the use of additive manufacturing for mass production. The problem raised in the context of this thesis is: How to make the process of sintering laser melting industrially viable? Our work focuses on the design and on the management of workshops integrating the additive manufacturing and of the complete process to obtain part according to three levels of decision: strategic, tactic and operational. About the strategic level, strong decisions of investment, machines selection and organization choice are taken with important economic issues. The aim is to define a multicriteria optimization method for the modular design of a production system integrating the additive manufacturing in the presence of uncertain data, optimal in the long term and the short term. From a tactical point of view, not all parts are necessarily relevant candidates for additive manufacturing. In this work, we developed a decision support tool that evaluates the relevance or not of additive manufacturing to obtain parts in a global cost approach. At the operational level, we offer a tool based on flow simulation that allows orders to be placed to production orders and their scheduling in order to guarantee the efficiency of the workshop. This research work is developed in collaboration with companies: AddUp, MBDA and Dassault, who contribute to our work and enable us to compare our tools with an industrial reality

Повний текст джерелаVat photopolymerization technologies are emerging quickly in the field of additive manufacturing. To follow this fast expansion of the market, highly efficient and affordable photosensitive resins are necessary. In this work, we introduce a new three-component phototiniating system (3K PIS) based on the Safranine O (SFH+) dye which has been identified as a very efficient initiator in several 3K PIS for photopolymerization processes.The dye is combined with a Tetraphenylborate salt (TPB) as electron donor and a Triazine derivative (TA) as electron acceptor to form a photochemical regenerating cycle. The photocycling mechanism is explored via laser flash photolysis (LFP) and the photopolymerization is investigated through Real-Time-Fourier Transform Infrared spectroscopy (RT-FTIR). Infrared experiments with several irradiances allow disclosure of an empirical model predicting conversion as a function of time and light intensity.Following this, cure depth experiments are conducted in agreement with Jacobs’ equation and the resin 3D printing parameters, i.e. critical energy (Ec) and penetration depth (Dp), are established. These parameters are linked to RT-FTIR data, resulting in the determination of the critical time (tc) and the conversion at gel point.Finally, high resolution complex pieces are printed with the resin which composition was tailored in accordance with our studies, demonstrating the viability of this formulation in DLP 3D printing

Повний текст джерелаThe "numerical materials" approach, developed at CEA Le Ripaut, consists to numerically optimize a structure, by using calculation codes that allow to realize numerical experiments, in order to answer, as precisely as possible, to a set of specifications. The manufacturing of these optimized structures, whose shapes can be complex, is sometimes not feasible with current manufacturing processes. However, the rapid progress of 3D printing now seems to be able to concretize this approach. The aim of this thesis is to study this manufacturing feasibility, through a concrete application: the optimization of the volumetric receivers of Concentrated Solar Power Plants (CSP). Currently, the design of these silicon carbide (SiC) receptors is restricted by the existing manufacturing techniques, and their morphologies are therefore mainly limited to foams or parallel channels. However, this type of structure does not allow to exploit all the 3D character proposed by the receivers, due in particular to a heterogeneous absorption of solar radiation in the volume. In this work, in order to find the distribution of the most homogeneous absorption possible in the whole volume, many structures with various shapes are generated virtually. A simulation of the solar irradiance received is carried out on all these structures, thanks to a calculation code developed especially for this application, thus allowing to choose three of them, respondents at best to the criteria of the specifications. These potentially optimized structures were then manufactured in SiC by 3D printing, by a binder jetting process. They were then tested on an experimental test bench of the PROMES laboratory, reproducing the conditions of a CSP. Results showed that these structures, where their shapes are totally different from foams or parallel channels, are able to produce a maximum air temperature of 860°C at the output of the receiver, and with efficiencies close to 0.65. Finally, a conducto-radiative coupled thermal computational code, improved during this work, made it possible to analyze these experimental results and will be used for the future work of optimization of the geometry of a receiver

Повний текст джерелаEmphasizing the integration of Additive Manufacturing (AM) into big industrial companies becomes crucial for subcontractors. Teaching additive processes and design rules is a techno-centric vision. It is not sufficient to project future applications of additive manufacturing in various industries such as aeronautics, energy, medical, etc. On one hand, the state of the art and field observations show that AM knowledge is steadily increasing. On the other hand, the state of the art about creativity shows that individuals creative capacity can be stimulated to guide them to the generation of creative ideas and concepts. This thesis then explores a possible linking between AM and creativity in order to propose a methodology and its application tools to stimulate creativity, in the specific context of additive manufacturing. This approach allowed us to bring out the major role of intermediate objects which articulate the interactions between several dimensions of the creative capacity: motivations, emotions, knowledge exploration, individual/collective work phases and spatial organization. It also highlighted the need for a new definition of intermediate objects’ roles regarding additive manufacturing. In this sense, we designed two operational devices, based on sensory manipulation of tangible objects, and tested them in real industrial contexts. Our experimental results show that the exploration of the knowledge embodied in these devices emphasizes the generation of creative ideas opening to potential applications of additive manufacturing. Finally, a model of Creativity Through Additive Manufacturing (CTAM) has been proposed. It enables us to contribute both to the methodological practices of design science and operational practices in two fields: the additive manufacturing industry and the field of innovation

Повний текст джерелаThe Selective Laser Melting Process (SLM) consists in manufacturing metallic parts by melting successive powders layers. This new additive manufacturing method allows building new complex geometries that can help lighten structures, such as lattice parts. However, the mechanical properties of additive manufacturing parts are still an industrial concern, especially for high cycle fatigue behavior. Such parts can indeed comprise surface and internal pores that can be deleterious to mechanical properties. The goal of this thesis is to characterize the influence of porous defects on the high cycle fatigue fatigue performance of 316L SLM parts. Firstly, some key SLM parameters that can control the porosity and the microstructure of fabricated parts were quantified. A distinction between the pore types was proposed, and their characteristics were related to the volumetric energy density delivered by the laser. The microstructure was also investigated, with a focus on crystallographic orientation and grain size, depending on the melt pool overlap and morphology. Secondly, using X-ray tomography, a parametric research was conducted to generate and characterize optimized fatigue samples with a minimal amount of pores. Such samples were used as a reference for other fatigue samples containing various randomly distributed pore populations, with similar microstructures. The relative influence of different internal pore populations on the high cycle fatigue endurance was quantified, for similar surface pore population. Finally, deterministic pores with controlled morphology, position and various dimensions were generated after a detailed parametric optimization. A specific internal crack initiation threshold was evidenced for deterministic defects, which was supposed to be linked to the local gaseous environment during crack initiation and propagation

Повний текст джерелаIndustry 4.0 highlights the need for massive data collection and therefore relies partly on the use of smart parts that are capable of providing data when they are used. In addition, metal additive manufacturing technologies seem to be a way to easily make smart parts and particularly the Wire & Arc Additive Manufacturing (WAAM) process that uses arc-welding technology. This raises the following issue, how to manufacture and design a smart metal part by WAAM? The research scope is limited to stress measurement in aluminum parts. In order to answer this problem, four scientific issues are identified and resolved in this manuscript:• The integration of a sensing technology within a part requires the part to be massive (composed of juxtaposed beads). Thus, making massive parts in aluminum is the first scientific challenge to resolve. Manufacturing parameters of the WAAM process are listed and explained in the state of the art. Wetting, regularity and mass energy of a bead are identified as indicators of the suitability of the selected parameters to be used to produce sound massive parts. Experimental campaigns are conducted to select parameters not identified by the state of the art to produce a wetted bead with low mass energy. Blocks are made and specimens are extracted then their mechanical characteristics are determined by tensile test in order to validate the selected parameters.• The second scientific challenge identified is to correctly choose the stress measurement technology to be inserted. Many devices that can be inserted during the WAAM process but also selection methods are reviewed in the bibliographic chapter. A synthesis in four families of strain measurement technologies relevant for the insertion during the WAAM process is therefore proposed. A selection guide based on evaluation criteria, on the knowledge of these technologies and on the specifications of parts to design as smart parts is proposed. Control by induction of an embedded magnetostrictive stress indicator is the most promising technology according to the proposed guide. This technology is used in the rest of the study.• The third challenge is to make the smart part manufacturable with the selected sensing technology. This technology requires the insertion of a thin steel indicator within the aluminum host part. In order to demonstrate its feasibility, various parameters (indicator’s coating, trajectory of the welding torch) are explored during experimental campaigns. Samples produced are analyzed by tomography. Thickness maps of the indicator are thus produced and allow to evaluate their deterioration. Scanning electron microscopy analysis of the intermetallic layer shows the fusion between the indicator and the host part and thus the feasibility of producing a smart part.• Finally, to realize a smart part with this technology, the last challenge is the choice of the indicator location in the part so that it reports the evolution of the stress in this one. Thus, recommendations for the selection of the mechanical characteristics of the indicator were formulated using the analysis of its magnetostrictive behavior and its mechanical coupling to its environment. Then, a method of placing the indicator for the measurement of the part maximum stress based on finite element simulations is presented for four distinct measurement scenarios.All the studies carried out allow to conclude on the interest of the use of the WAAM process for the production of smart parts

Повний текст джерелаAdditive Manufacturing (AM) has enabled the building of parts with new shapes and geometrical features. As this technology modifies the practices, new knowledge is required for designing and manufacturing properly. To help experts create and share this knowledge through formalization, this research work focuses on knowledge elicitation, analysis and structuring. After defining knowledge concepts we present the SoA in knowledge elicitation and classification. Three case studies present different approaches to capture AM knowledge. The first one points out the assets and limits of three individual elicitation techniques. The second one describes tools and techniques to elicit and structure knowledge about support structures for EBM parts. The last one proposes a method to model AM process rules in relation with EBM technology. As a conclusion, we provide some propositions and recommendations for a better elicitation and formalization of AM knowledge

Повний текст джерелаThe PhD thesis deals with the fatigue performance of steels manufactured by Powder Bed Fusion using a laser beam (L-PBF). The objective of the study is to develop a method for the rapid and reliable characterization of the produced material’s fatigue limit using infrared (IR) thermography. Preliminary conventional fatigue tests were performed, revealing two distinct populations among the printed specimens depending on their locations on the building plate. Next, fatigue tests instrumented by IR camera were processed using heat source reconstruction to measure the mechanical dissipation due to fatigue damage. A statistical model was then proposed to identify the fatigue limit of the material. Finally, a practical application was performed to compare different manufacturing strategies using the same powder of maraging steel, as well different steels (maraging, L40 and W360). The results open perspectives for the rapid optimization of the printing process with respect to the fatigue performance of the parts produced
