En esta tesis doctoral se desarrolla un procedimiento para estimar la vida a fatiga de sistemas de implantes dentales. Dicha metodología consiste en la aplicación, a dichos implantes, de varios modelos de predicción de vida a fatiga. El uso de estos modelos requiere del conocimiento de distintas propiedades mecánicas del material en que están...

En este artículo se estudia el sistema de fijación de implantes dentales empleado en los ensayos de fatiga realizados para su cualificación. Según la norma UNE-EN ISO 14801 se permiten varias opciones, por ejemplo embebidos en un soporte o mediante algún tipo de mordaza mecánica. Sin embargo, ensayos...

This paper presents two multiaxial fatigue life prediction models applied to a commercial dental implant. One model is called Variable Initiation Length Model and takes into account both the crack initiation and propagation phases. The second model combines the Theory of Critical Distance with a critical plane damage model to characterise the...

En este artículo se estudia el comportamiento ante la fatiga de implantes dentales de titanio comercialmente puro grado 4. Dichos implantes se ven sometidos a ciclos de carga y descarga durante la masticación, lo cual produce sobre el implante la acumulación de daño por fatiga y una posible rotura. En el trabajo se...

A new reciprocating scintillator based fast-ion loss detector has been installed a few centimeters above the outer divertor of the ASDEX Upgrade tokamak and between two of its lower Edge Localized Modes (ELM) mitigation coils. The detector head containing the scintillator screen, Faraday cup, calibration lamp, and collimator systems are...

Dental implants need to pass a certification where their fatigue strength is determined following the international standard ISO 14801. This standard distinguishes between straight and pre-angled connecting parts. In some countries, it is obligatory to obtain the fatigue curve for the pre-angled implant ...

Nuclear fusion is expected to be a clean and almost-unlimited power source in the near future. The first net power demonstration plant (DEMO) is planned to start operation in 2050. The supercritical carbon dioxide (S-CO2) Brayton cycle is an excellent candidate for integration with a fusion power plant, such as DEMO, because of its high...

JT-60SA, the largest tokamak that will operate before ITER, has been designed and built jointly by Japan and Europe, and is due to start operation in 2020. Its main missions are to support ITER exploitation and to contribute to the demonstration fusion reactor machine and scenario design. Peculiar properties of JT-60SA are its capability to...

A new spherical tokamak, the SMall Aspect Ratio Tokamak (SMART), is currently being designed at the University of Seville. The goal of the machine is to achieve a toroidal field of 1 T, a plasma current of 500 kA and a pulse length of 500 ms for a plasma with a major radius of 0.4 m and minor radius of 0.25 m. This contribution presents the...
