Full textA general constitutive framework is proposed to incorporate linear and nonlinear mechanical behaviour laws (i. G. Elastoviscoplasticity) into a standard phase field model. A finite element formulation of a coupled phase field/diffusion/mechanical problem for alloys is proposed within the general framework of continuum thermodynamics. This formulation is based on the concept of generalized stresses as proposed by Gurtin, where an additional balance equation for generalized stresses, called microforces, associated with the order parameter and its first gradient, is postulated. The formulation is used to simulate the complex morphological evolutions of the heterogeneous microstructures and to describe the diffuse interface between two phases in the presence of the stresses induced by phase transformation. Using the principles of the thermodynamics of irreversible processes, the balance and constitutive equations are clearly separated in the formulation. Also, boundary and initial conditions for the displacement, concentration and order parameter and their dual quantities are clearly stated within the formulation. The theory is shown to be well-suited for a finite element formulation of the initial boundary value problems on nite size specimens with arbitrary geometries and for very general non-periodic or periodic boundary conditions. In the diffuse interface region where both phases coexist, mixture rules taken from homogenization theory are introduced into the formulation. The consequences of the choice of a specific interface behaviour is investigated, with regard to the mechanical effect on phase equilibria (equilibrium compositions and volume fractions of the coexisting phases), as well as on the transformation kinetics. The set of coupled evolution equations, which are the local static equilibrium, the balance of generalized stresses and the balance of mass, is solved using a finite element method for the space discretization and a finite difference method for the temporal discretization. To validate the numerical finite element implementation and to illustrate the ability of the proposed model to handle precipitation together with mechanical contribution effect, some elementary initial boundary value problem in coupled diusion-elasto-plasticity on finite size specimens has been solved and validated against corresponding sharp interface analytical solutions

Full textWelding is a highly used assembly technique. Welding simulation software would give access to residual stresses and information about the weld's microstructure, in order to evaluate the mechanical resistance of a weld. It would also permit to evaluate the process feasibility when complex geometrical components are to be made, and to optimize the welding sequences in order to minimize defects. This work deals with the numerical modelling of arc welding process of steels. After describing the industrial context and the state of art, the models implemented in TransWeld ( software developed at CEMEF) are presented. The set of macroscopic equations is followed by a discussion on their numerical implementation. Then, the theory of remeshing and our adaptive anisotropic remeshing strategy are explained. Two welding metal addition techniques are investigated and are compared in terms of the joint size and transient temperature and stresses. The accuracy of the finite element model is evaluated based on experimental results and the results of the analytical solution. Comparative analysis between experimental and numerical results allows the assessment of the ability of the numerical code to predict the thermomechanical and metallurgical response of the welded structure. The models limitations and the phenomena identified during this study are finally discussed and permit to define interesting orientations for future developments

Full textThis work is a part of study which goal is to realize a computer modelling of the thermomechanical phenomena occurring during the YAG pulse laser welding of titanium alloy (TA6V). The filet welding has different heterogeneities (microstructural and mechanical). In fact, the temperature causes microstructural changes (phase transformations, precipitation…) and modifies the mechanical properties. Thermomechanical modelling has thus to be established for the welding of TA6V. In this study, we focus on the identification of the different phase transformations occurring during the welding, during the heating and the cooling. Then we define the conditions for which the mechanical behavior of these different phases has to be characterized in order to obtain the residual stresses and the residual strains of this welded part. A thermometallurgical and mechanical modelling will thus be proposed for the YAG pulse laser welding of TA6V. The behavior of material after laser welding can be described by three fundamental data (field of temperature, metallurgical state and fields of stress/strain). We have identified and modelled the different phenomena and several stages are to be considered : Determination of the metallurgical phase transformations during the deposit of energy and the cooling ; Experimental Characterization of the mechanical behavior of each phase under the purposeful conditions of temperatures and strains ; Modeling of the thermomechanical behavior by a thermo-elasto-viscoplastic law integrating phase transformation, in order to quantify the strains and the residual stresses observed in the assemblies ; Validation of the model with a welding instrumented test

Full textThe precipitation, which is an important phase transformation in condensed matter physics, has been studied in this PhD thesis. A thermodynamic model accounting for the observed increase of the solute content in coherent precipitates with their size during precipitation kinetics is developed. The model is based on a Gibbs energy minimization criterion. It proves the importance of the elastic and interfacial energies in investigating the thermodynamic stability of coherent nano-precipitates. The reliability of the model is confirmed by experimental results. The precipitation kinetics in multicomponent alloys is treated with a particle size distribution model where analytical equations of nucleation, growth and coalescence are integrated numerically. This powerful numerical tool for the description of kinetic paths is valid for weakly supersaturated solid solutions and is not time consuming. It provides information on complex compositions evolutions during the transformation due to the competition between thermodynamics and diffusion process. This thesis also discusses the concepts and limits of classical nucleation theory. The reliability of the nucleation rate expression is investigated in terms of supersaturation. It is shown that even if a proper trend is obtained, the results are not quantitative since the matrix depletion has not been taken into account. To compare some of our results with experiments, precipitation patterns in the CuAg binary alloy are studied by TEM

Full textIn this thesis, two problems related to compositional multiphase flow in porous media have been treated. The first part is devoted to develop a new approach which gives a form of equilibrium equations which can be solved analytically even for multi-component non ideal systems and even in the presence of capillary effects, which reduce significantly computational time. In this approach, separate behaviors of gas, liquid and two phase fluid may be described using very simple equations of state (EOS). Capacity of EOS?s to capture two phase state is called: consistency conditions. These conditions are formulated in this part for multi-components systems. The second part is devoted to develop the negative saturations method which was proposed earlier by our group for the case of two-phase binary mixtures. First, we have developed the mathematical theory of the method for ideal mixtures in 1D case. Next, we have generalized the method for the case of any number of phases and chemical components. We have obtained the new equivalent uniform multi-phase equations which contain additional non-classical terms responsible of diffusion and gravity across the interfaces of phase transition

Full textCapillary pumped loop is a two phase device that uses the phase change phenomena occurred in the porous wick to transport large heat loads over long distances (several meters) without the need of any mechanical pump. CPLs have been developed and successfully employed for the thermal control of satellites. Thanks to their heat transport capacity, their use is now seriously considered in the gravity field especially for cooling electronic devices of a railroad traction chain. The work of this thesis focuses on the description of the unsteady thermodynamic behavior of a capillary pumped loop used by Alstom Transport to cool its power electronics components. The first part of the thesis consists to study the key component of CPL: the capillary evaporator. A 2D unsteady mathematical model has been developed to describe the heat and mass transfer inside the porous wick of the CPL evaporator. The numerical results of this model show the formation of a vapor pocket inside the porous wick. The influences of evaporator geometry, liquid subcooling, saturation temperature and wick porosity on the dynamic growth of the vapor pocket are discussed in detail. The second part of this work consists of coupling the CPL evaporator model with other CPL components in order to obtain a global capillary pumped poop model with a mobile liquid/vapor interface in the porous wick. The proposed model is validated by comparing numerical simulations with experimental results obtained in a previous works realized at Alstom Transport. The CPL startup is then studied. Finally, the influences of the applied power, reservoir temperature and heat sink temperature on the dynamic response of the overall loop are analyzed, with a particular interest to the evaporator behavior
