Conceptual design of the ITER fast-ion loss detector
(AIP Publishing, 2016-11)
A conceptual design of a reciprocating fast-ion loss detector for ITER has been developed and is presented here. Fast-ion orbit simulations in a 3D magnetic equilibrium and up-to-date first wall have been carried out to ...

¿Por qué siguen produciéndose fallos por fatiga? Descripción de 2 casos paradigmáticos
(Grupo español de fractura, 2012)
Los criterios de diseño que permiten evitar fallos por fatiga están, en general, bien establecidos, tanto desde un punto de vista científico como desde una perspectiva de la ingeniería más aplicada. Puede decirse que los ...

Aplicación de la mecánica de fluidos y la simulación: Tracto urinario y catéteres ureterales
(INIESTARES S.A., 2016)
The mechanics of urine during its transport from the renal pelvis to the bladder is of great interest for urologists. The knowledge of the different physical variables and their interrelationship, both in physiologic ...

Analysis of initial crack path in fretting fatigue
(Gruppo Italiano Frattura (IGF), 2016)
The initial crack path is analysed in a fretting fatigue test with cylindrical contact, where there is a stress gradient and a multiaxial and non-proportional stress state. For this, a cylindrical pad is pressed, with ...

Efecto del modelo geométrico en la predicción de vida a fatiga por fretting
(Grupo español de fractura, 2014)
Este trabajo estudia la influencia que tiene en la estimación de la vida a fatiga por fretting el tipo de geometría utilizada para calcular los estados de tensiones/deformaciones producido en un par de contacto cilindro-plano. ...

Elastic properties of woven bone: effect of mineral content and collagen fibrils orientation
(Springer, 2017)
Woven bone is a type of tissue that forms mainly during fracture healing or fetal bone development. Its microstructure can be modeled as a composite with a matrix of mineral (hydroxyapatite) and inclusions of collagen ...

Biaxial fatigue tests of notched specimens for AISI 304L stainless steel
(Gruppo Italiano Frattura (IGF), 2016)
High cycle fatigue tests were conducted for stainless steel AISI 304L. The geometry was a thin walled tube with a passing through hole. The tests were axial, torsional and in-phase axial-torsional, all of them under load ...

On the Use of Maximum Force Criteria to Predict Localised Necking in Metal Sheets under Stretch-Bending
(MDPI, 2017-11-02)
The maximum force criteria and their derivatives, the Swift and Hill criteria, have been extensively used in the past to study sheet formability. Many extensions or modifications of these criteria have been proposed to ...

Non-linear vibrating systems excited by a nonideal energy source with a large slope characteristic
(Academic Press, 2017)
This paper revisits the problem of an unbalanced motor attached to a fixed frame by means of a nonlinear spring and a linear damper. The excitation provided by the motor is, in general, nonideal, which means it is affected ...
