Esta tese é focada no desenvolvimento e na análise de aproximações em dimensão finita das equações que descrevem problemas de elasticidade linear e poroelasticidade. A estratégia de aproximação é baseada em formulações de elementos finitos mistas hibridas desses problemas e a construção dos espaços de dimensão finita é guiada por várias propriedades desejadas: continuidade das trações (conservação do momento linear), simetria do tensor de tensão (conservação do momento angular), número reduzido de graus de liberdade globais e robustez sob distorção de malha. A principal dificuldade está relacionada com o atendimento simultâneo da condição inf-sup e da simetria do tensor de tensão. O ultimo requisito é relaxado, sendo satisfeito de maneira fraca pela introdução de um multiplicador de Lagrange. A maior contribuição é o desenvolvimento e a análise de espaços de dimensão finita estáveis para aproximação mista dos problemas de elasticidade linear e poroelasticidade em malhas quadrilaterais arbitrárias. Esses espaços são capazes de fornecer convergência com taxa ótima do campo de tensão na norma H(div) em malhas de quadriláteros arbitrários, o que é provado pela análise numérica e confirmado por experimentação.
This thesis is focused on the development and analysis of finite dimensional approximations of the equations describing linear elasticity and poroelasticity problems. The approximation strategy is based on mixed hybrid finite element formulations of those problems and the construction of the finite dimensional spaces is guided by several desired properties: continuity of the tractions (conservation of linear momentum), symmetry of the stress tensor (conservation of angular momentum), reduced number of global degrees of freedom, and robustness under mesh distortion. The main difficulty is related with the simultaneous fulfillment of the inf-sup condition and the symmetry of the stress tensor. The last requirement is relaxed, being enforced in the weak sense through the introduction of a Lagrange multiplier. The main contribution is the development and analysis of stable finite dimensional spaces for mixed approximation of linear elasticity and poroelasticity problems on arbitrary quadrilateral meshes. These spaces are capable of providing optimal order convergence of the stress field in the H(div)-norm on meshes of arbitrary quadrilaterals, which is proved by numerical analysis and confirmed by experimentation.

Full textHybridstegsmotorer appliceras i fler ochfler industriapplikationer tack vare deras låga kostnad och förbättrad prestanda jämfört med servomotorer. Många branschapplikationer kräver exakta och effektiva metoder för att förutsäga motorns prestanda redan i konstruktionsstadiet. Motorns geometri är komplicerad och den magnetiska mättnadseffekten är också betydande, vilket försvårar modelleringen. Dessutom är drivkretsen och styralgoritmen mer sofistikerad än den för traditionella växeleller likströmsmotorer. Vidare så resulterar motorns förluster i temperaturökningar vilka påverkar dynamiska.Alla dessa faktorer kan studeras genom att simulera hybrida stegmotorer med en modell som kombinerar effekten av elektromagnetiskt fält, kontrollalgoritm och motorförluster tillsammans. I detta examensarbete utvecklas en tredimensionell finit elementmodell i programvaran Maxwell för att studera motorns elektromagnetiska egenskaper. Det elektromagnetiska fältet analyseras i ett statiskt tillstånd. Den beräknade mot-EMK:n har verifieras genom experiment. Vektorkontrollalgoritmen tillämpas på modellen genom samsimulering i Simulink och Maxwell i Simplorer. Den tredimensionella modellen visade sig vara orealistisk för samsimulering. Till sist summeras uppnådaerfarenheter och rekommendationer för fortsatt arbete ges.

Full textENGLISH ABSTRACT: A two-dimensional Coupled Element Method (CEM) for solving electromagnetic scattering problems involving lossy, inhomogeneous, arbitrarily shaped cylinders, was investigated and implemented. The CEM uses the Finite Element Method (FEM) to approximate the fields in and around the scatterer and the Boundary Element Method (BEM) to approximate the far-field values. The basic CEM theory is explained using the special, static electric field problem involving the solution of Laplace's equation. This theory is expanded to incorporate scattering problems, involving the solution of the Helmholtz equation. This is done for linear as well as quadratic elements. Some of the important algorithms used to implement the CEM theory are discussed. Analytical solutions for a round, homogeneous- and one layer coated PC cylinder are discussed and obtained. The materials used in these analytical solutions can be lossy as well as chiral. The CEM is validated by comparing near- and far-field results to the analytical solution. A comparison between linear and quadratic elements is also made. The theory of the CEM is further expanded to incorporate scattering from chiral media
AFRIKAANSE OPSOMMING: 'n Gekoppelde Element Metode (GEM) wat elektromagnetiese weerkaatsingsprobleme, van verlieserige, nie-homogene, arbitrere voorwerpe kan oplos, is ondersoek en geimplimenteer. Die GEM gebruik die Eindige Element Metode (EEM) om die velde in en om die voorwerp te benader. 'n Grenselementmetode word gebruik om die vervelde te benader. Die basiese teorie van die GEM word verduidelik deur die toepassing daarvan op die spesiale geval van 'n statiese elektriese veld- probleem. Hierdie probleem verlang die oplossing van Laplace se vergelyking. Die teorie word uitgebrei om weerkaatsingsprobleme te kan hanteer. Die weerkaatsingsprobleme verlang die oplossing van 'n Helmholtz-vergelyking. Hierdie teorie word ontwikkel vir lineere sowel as kwadratiese elemente. Van die belangrike algoritmes wat gebruik is om die GEM-teorie te implimenteer, word bespreek. Analietise oplossings vir ronde, homogene en eenlaag bedekte perfek geleidende silinders word bespreek en verkry. Die material wat in die oplossings gebruik word, kan verlieserig of kiraal wees. Die GEM word bekragtig deur naby- en verveld resultate te vergelyk met ooreenkomstige aitalitiese oplossings. Die lineere en kwadratiese element- resultate word ook met mekaar vergelyk. Die GEM-teorie is verder uitgebrei sodat weerkaatsing vanaf kirale materiale ook hanteer kan word.

Full textTo solve wave equations in heterogeneous media with finite elements with a reasonable numerical cost, we couple the Discontinuous Galerkin method (DGm) with Spectral Elements method (SEm). We use hybrid meshes composed of tetrahedra and structured hexahedra. The coupling is carried out starting from a mixed-primal DG formulation applied on a hybrid mesh composed of a hexahedral macro-element and a sub-mesh composed of tetrahedra. The SEm is applied in the macro-element paved with structured hexahedrons and the coupling is ensured by the DGm numerical fluxes applied on the internal faces of the macro-element common with the tetrahedral mesh. The stability of the coupled method is demonstrated when time integration is performed with a Leap-Frog scheme. The performance of the coupled method is studied numerically and it is shown that the coupling reduces numerical costs while keeping a high level of accuracy. It is also shown that the coupled formulation can stabilize the DGm applied in areas that include Perfectly Matched Layers
Dang, Weidong. "Finite element modelling of hybrid (spot welded/bonded) joints under service conditions." Thesis, Compiègne, 2015. http://www.theses.fr/2015COMP2187/document.
Full textSpot welding and adhesive bonding are widely used in joining of sheet metals, such as assembling of car body-in-white. Recently, spot weld and adhesive are combined to make weld bonded joint, which is employed to join Advanced High Strength Steel to improve the stiffness and crashworthiness of car body. In industry, the assessment of designing prior to prototype requires reliable constitutive models in terms of the prediction of the mechanical behaviors. The FE model of weld bonded joint is a new challenge as it should combine the models of spot welding and the models of adhesive. This thesis focuses on the modeling of weld bonded joint by DP600 steel and structural adhesive SikaPower®-498. The model of weld bonded joint consists of solid model and simplified model. The former is devoted to predict the behavior of weld bonded joint on small-scale specimen: KS2 and lap-shear. The latter can be used to predict the performance of large components with acceptable computational cost. As regards solid model, spot welded joint and adhesive bonded joint behaviors are separately identified by KS2 specimen under different loading path. The inhomogeneities in fusion zone and heat affected zone of spot weld are taken into account via the scaling of the flow stress of base metal. The scaling factors are calibrated by inverse identification. Gurson model is used to predict ductile fracture in heat affected zone and base metal while cohesive zone model is employed to simulate quasi-brittle fracture in the interface of fusion zone. The parameters of cohesive zone model are identified by the J-integral at the notch tip of spot weld crack. Cohesive zone elements with traction-separation-laws are also used to predict adhesive debonding. Model parameters are calibrated by Double Cantilevered Beam and End Notched Flexure specimens, corresponding to Mode-I and Mode-II fracture respectively. The model developed for spot weld is associated with adhesive model to predict weld bonded joint. As regards simplified model, connector elements are employed to predict the damage of spot weld. The parameters of connector element are identified by KS2 tests under different loading paths. Finally, the simplified model of spot welding, adhesive bonding, and weld-bonding are validated by T-joint which can represent the B-pillar of car body

Full textAmong the special features of the model are the casting of the element stiffness equations in terms of local rather than global coordinate system, the use of the active column method known as the "Skyline technique for the solution of equilibrium equations", and the use of fast and efficient mesh generation and alteration routines developed specially for geotechnical applications.
Verification tests carried out on problems in elasticity with closed form solutions show that the proposed method is accurate and that it requires relatively fewer elements than displacement-based finite element method to achieve the same accuracy. Results of case history studies done on two mine design problems matched those from other numerical modelling procedures within acceptable limits and showed that the proposed method can be used to solve geomechanics problems efficiently and realistically.

Full textIn the present work, the partition of unity enrichment concept is basically applied to non-conventional stress hybrid-mixed and hybrid formulations in plane elasticity. These formulations are referred to as non-conventional because no variational principles are explored. From these, triangular and quadrilateral finite elements with selective nodal enrichment are then derived. In the stress hybrid-mixed approach, three independent fields are approximated: stress and displacement fields in the domain and displacement fields on the static boundary. The partition of unity concept is then used to provide continuity to all the fields involved. Afterwards, the nodal enrichment feature is explored. Polynomial functions are employed to enrich each one of the approximation fields. Besides, some aspects concerning convergence and stability of the numerical solutions obtained are addressed. On the other hand, in the hybrid approach, two independent fields are approximated: stress fields in the domain and displacement fields on the static boundary. However, the approximation of the stress field must first satisfy the equilibrium condition in the domain without involving nodal values in its definition. Hence, the partition of unity concept is used to provide continuity of displacements between the boundaries of the elements. The partition of unity based nodal enrichment is then applied to the boundary displacement fields. Nevertheless, enrichment of the stress field can also be carried out with exploring a specific and original technique that permits applied the partition of unity concept but in such way as to preserve satisfaction of the equilibrium condition in the domain. Again, convergence and stability aspects of the hybrid approach are briefly addressed. Finally, some numerical examples are presented to illustrate the performance of both approaches derived, especially when combined possibilities of enrichment are explored.

Full textThe Finite Element Method (FEM) as applied to Computational Electromagnetics (CEM), can beused to solve a large class of Electromagnetics problems with high accuracy and good computational efficiency. For solving wide-band problems time domain solutions are often preferred; while time domain FEM methods are feasible, the Finite Difference Time Domain (FDTD) method is more commonly applied. The FDTD is popular both for its efficiency and its simplicity. The efficiency of the FDTD stems from the fact that it is both explicit (i.e. no matrices need to be solved) and second order accurate in both time and space. The FDTD has limitations when dealing with certain geometrical shapes and when electrically large structures are analysed. The former limitation is caused by stair-casing in the geometrical modelling, the latter by accumulated dispersion error throughout the mesh. The FEM can be seen as a general mathematical framework describing families of concrete numerical method implementations; in fact the FDTD can be described as a particular FETD (Finite Element Time Domain) method. To date the most commonly described FETD CEM methods make use of unstructured, conforming meshes and implicit time stepping schemes. Such meshes deal well with complex geometries while implicit time stepping is required for practical numerical stability. Compared to the FDTD, these methods have the advantages of computational efficiency when dealing with complex geometries and the conceptually straight forward extension to higher orders of accuracy. On the downside, they are much more complicated to implement and less computationally efficient when dealing with regular geometries. The FDTD and implicit FETD have been combined in an implicit/explicit hybrid. By using the implicit FETD in regions of complex geometry and the FDTD elsewhere the advantages of both are combined. However, previous work only addressed mixed first order (i.e. second order accurate) methods. For electrically large problems or when very accurate solutions are required, higher order methods are attractive. In this thesis a novel higher order implicit/explicit FETD method of arbitrary order in space is presented. A higher order explicit FETD method is implemented using Gauss-Lobatto lumping on regular Cartesian hexahedra with central differencing in time applied to a coupled Maxwell’s equation FEM formulation. This can be seen as a spatially higher order generalisation of the FDTD. A convolution-free perfectly matched layer (PML) method is adapted from the FDTD literature to provide mesh termination. A curl conforming hybrid mesh allowing the interconnection of arbitrary order tetrahedra and hexahedra without using intermediate pyramidal or prismatic elements is presented. An unconditionally stable implicit FETD method is implemented using Newmark-Beta time integration and the standard curl-curl FEM formulation. The implicit/explicit hybrid is constructed on the hybrid hexahedral/tetrahedral mesh using the equivalence between the coupled Maxwell’s formulation with central differences and the Newmark-Beta method with Beta = 0 and the element-wise implicitness method. The accuracy and efficiency of this hybrid is numerically demonstrated using several test-problems.
