Повний текст джерелаLas principales aportaciones de la tesis son: el desarrollo de una formulación ALE para modelos hyperelastoplásticos y el cálculo de operadores tangentes para distintas leyes constitutivas y esquemas de integración temporal no triviales (uso de esquemas de derivación numérica, técnicas de subincrementación y modelos elastoplásticos con endurecimiento y/o reblandecimiento dependientes del trabajo plástico o la densidad). Se presentan diversas aplicaciones que muestran las principales características de los desarrollos presentados (análisis del ensayo del molinete para arcillas blandas, del ensayo triaxial para arenas, de la rotura bajo una cimentación, del proceso de estricción de una barra metálica circular y de un proceso de estampación en frío), dedicando una especial atención a los aspectos computacionales de la resolución de dichos problemas. Por último, se dedica un capítulo específico a la modelización y la simulación numérica de procesos de compactación fría de polvos metálicos y cerámicos.
Numerical modelling of problems involving geomaterials (i.e. soils, rocks, concrete and ceramics) has been an area of active research over the past few decades. This fact is probably due to three main causes: the increasing interest of predicting the material behaviour in practical engineering situations, the great change of computer capabilities and resources, and the growing interaction between computational mechanics, applied mathematics and different engineering fields (concrete, soil mechanics...). This thesis fits within this last multidisciplinary approach. Based on constitutive modelling and applied mathematics and using both languages the numerical simulation of some complex geomechanical problems has been studied.
The state of the art regarding experiments, constitutive modelling, and numerical simulations involving geomaterials is very extensive. The thesis focuses in three of the most important and actual ongoing research topics within this framework: 1) the treatment of large boundary displacements by means of Arbitrary Lagrangian-Eulerian (ALE) formulations; 2) the numerical solution of highly nonlinear systems of equations in solid mechanics; and 3) the constitutive modelling of the nonlinear mechanical behaviour of granular materials. The three topics have been analysed and different contributions for each one of them have been developed. Moreover, some of the new developments have been applied to the numerical modelling of cold compaction processes of powders. The process consists in transforming a loose powder into a compacted sample through a large volume reduction. This problem has been chosen as a reference application of the thesis because it involves large boundary displacements, finite deformations and highly nonlinear material behaviour. Therefore, it is a challenging geomechanical problem from a numerical modelling point of view.
The most relevant contributions of the thesis are the following: 1) with respect to the treatment of large boundary displacements: quasistatic and dynamic analyses of the vane test for soft materials using a fluid-based ALE formulation and different non-newtonian constitutive laws, and the development of a solid-based ALE formulation for finite strain hyperelastic-plastic models, with applications to isochoric and non-isochoric cases; 2) referent to the solution of nonlinear systems of equations in solid mechanics: the use of simple and robust numerical differentiation schemes for the computation of tangent operators, including examples with several non-trivial elastoplastic constitutive laws, and the development of consistent tangent operators for different substepping time-integration rules, with the application to an adaptive time-integration scheme; and 3) in the field of constitutive modelling of granular materials: the efficient numerical modelling of different problems involving elastoplastic models, including work hardening-softening models for small strain problems and density-dependent hyperelastic-plastic models in a large strain context, and robust and accurate simulations of several powder compaction processes, with detailed analysis of spatial density distributions and verification of the mass conservation principle.

Повний текст джерелаAluminium forms a highly neurotoxic complex with maltol (3-hydroxy-2-methyl-4H-pyran-one). The stability of this complex has been determined using glass-electrode potentiometry. Owing to the effect on nuclear relaxation behaviour, paramagnetic contrast agents have immense diagnostic potential and have recently received a great deal of attention in the literature. The gadoliniummaltol complex was studied with the view to developing a potential tissue-specific magnetic resonance imaging contrast agent. Because of the interest in medical applications of radioactive isotopes of group 1118 elements, the indium-maltol complex was studied in order to assess its radiopharmaceutical usefulness. The major analytical techniques used in this study are potentiometry and high resolution nuclear magnetic resonance spectroscopy.

Повний текст джерелаL'obiettivo principale di questa tesi è quello di fornire strategie di modellazione e ottimizzazione efficienti per un dispositivo elettromagnetico noto come ingranaggio magnetico. In particolare modelli magnetici, termici e meccanici sono esaminati includendo materiali non lineari, algoritmi di smagnetizzazione magneti permanenti e modelli di isteresi in nuclei laminati. Dal punto di vista della modellazione magnetica, un approccio analitico per la progettazione semplificata dell'ingranaggio è presentata. Particolare attenzione viene data all'onere computazionale del metodo che è particolarmente adatto alle procedure di ottimizzazione stocastica. Per l'analisi dettagliata degli ingranaggi magnetici, un algoritmo basato sull'accoppiamento Finite Element / Boundary Element viene proposto, comprese le non linearità ferromagnetiche, le equazioni differenziali meccaniche, correnti parassite ed equazioni circuitali. Modelli dettagliati sono introdotti e discussi per analizzare gli effetti dell'isteresi dei materiali dolci e magnetizzazione, smagnetizzazione e recoil di magneti permanenti. Vengono anche investigati i meccanismi di perdita negli ingranaggi magnetici e le perdite di trasmissione al variare delle velocità di rotazione e gli angoli di carico. Un modello meccanico semplificato dell'ingranaggio magnetico è presentato e formulato come un insieme dei vincoli di disuguaglianza, fornendo così un collegamento diretto alle strategie di ottimizzazione. I vincoli meccanici includono gli spostamenti e le sollecitazioni dei poli ferromagnetici e le limitazioni sulla velocità di rotazione dovuta a sforzi eccessivi, risonanze e vibrazioni. Un'analisi semplificata basata su una rete termica equivalente è presentato, nella quale si considera anche il flusso di raffreddamento assiale. Le tecniche di ottimizzazione stocastica sono discusse per una progettazione multi-fisica della macchina ottimizzata e il modello analitico è incorporato in uno schema di evoluzione differenziale. Infine, i risultati ottimizzati sono discussi e confrontati con le soluzioni meccaniche commerciali. Viene inoltre proposta e analizzata una soluzione basata sulla connessione delle barre assiali che garantiscono un effetto di smorzamento quando la marcia dell'ingranaggio diventa asincrona. Tutti gli algoritmi sono stati convalidati tramite confronto con codici commerciali o, quando possibile, con i dati di esperimenti recuperati dalla letteratura.
