Análisis de la fractura interlaminar en modo I de laminados unidireccionales y angulares.
(2017-12-01)
El objetivo principal de la presente tesis doctoral es analizar la fractura interlaminar en modo I de laminados compuestos. Se ha realizado un análisis del ensayo DCB y de los métodos de reducción de datos.En este trabajo ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
Caracterización de hormigones especiales con mejora de sus propiedades térmicas para el desarrollo de sistemas prefabricados de cerramientos de bloque.
(2018-09-17)
Cuestiones ambientales como el calentamiento global, el agotamiento de los recursos naturales, la contaminación del agua, el aire y el suelo, la generación de enormes cantidades de residuos y subproductos, y las consecuencias ...
Optimización de la sostenibilidad energética en edificaciones residenciales: una aplicación al caso de la República Dominicana
(2018-09-17)
El desarrollo de los países está generando una serie de problemas a nivel mundial que están provocando cambios en el clima, que en la mayoría de los casos afectan en gran medida a las familias con menores recursos. De igual ...
Calibration patterns for predicting residual strengths of steel fibre reinforced concrete (SFRC)
(Elsevier, 2013-11-12)
Steel Fibre Reinforced Concrete (SFRC), a composite construction material, needs reliable prediction and control techniques to promote its use in structural applications. The distribution and orientation of fibres within ...
Modeling the environmental sustainability of timber structures: a case study
(Elsevier, 2019-07-16)
A revival in timber buildings and the appreciation of their positive physical and mechanical properties can be explained by the unique environmental credentials of timber products and their versatility. Heightened public ...
Sustainability Improvement in the Design of Lightweight Roofs: A New Prototype of Hybrid Steel and Wood Purlins
(MDPI, 2019-01-01)
A new structural typology of a hybrid purlin, made of type C cold steel and rectangular laminated wood (SWP), is presented in this paper. As a result, improvements on the most commonly used steel purlins are achieved, by ...
Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
(MDPI, 2018-06)
Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to ...
Static structural behaviour of wire bearings: comparison with conventional bearings and study of design and operational parameters
(Elsevier, 2018-10-28)
In wire bearings the rolling process occurs on raceways machined on steel wires, and the rings are
made of light materials such as aluminium. This particular architecture provides both weight and
inertia savings, but ...
A novel procedure to determine the cohesive law In DCB tests
(Elsevier, 2017-11-10)
A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the ...
