Rigid pavement performance models by means of Markov Chains with half-year step time
(Taylor & Francis, 2019-07-03)
[EN] Pavement management systems employ pavement performance models to plan the most effective allocation of public funds. The most used models are the deterministic and the probabilistic or stochastic ones. Among stochastic ...
Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
(Elsevier, 2017-07-14)
The melt pool dynamics consideration in the numeric modeling of the Laser Material Deposition (LMD) process can be enormously difficult and expensive, especially if this calculation is not strictly necessary. The increased ...
Experimental assessment of an End Notched Flexure test configuration with an inserted roller for analyzing mixed-mode I/II fracture toughness
(Elsevier, 2016-09)
This study describes the experimental work related to a test configuration proposed recently, based on an End Notched Flexure test configuration modified with an inserted roller. Various mixed-mode ratio tests have been ...
Instantaneous powder flux regulation system for Laser Metal Deposition
(Elsevier, 2017-09-04)
A new control system for regulating the powder flux during the laser metal deposition process (LMD) has been designed, developed and validated. The powder regulation system is based on a solenoid, which is coupled to the ...
Hardness, grainsize and porosity formation prediction on the Laser Metal Deposition of AISI 304 stainless steel
(Elsevier, 2018-08-14)
[EN] The presented numerical model solves the heat and mass transfer equations in the Laser Metal Deposition process and based on the evolution of the thermal field predicts the grainsize, the resulting hardness and evaluates ...
Equivalent Energy Release Rate And Crack Stability In The End Notched Flexure With Inserted Roller Mixed Mode I/II Test
(Elsevier, 2017-02)
The crack propagation performance of the End Notched Flexure with inserted roller test is analyzed. An equivalent energy release rate is proposed taking into account the interaction of the modes I and II, based on the ...
In-plane shear behaviour of multiscale hybrid composites based on multiwall carbon nanotubes and long carbon fibres
(Sage, 2015-09-18)
Both in-plane shear modulus and in-plane shear strength of multiscale hybrid composites have been studied. Carbon fibre-based laminates have been fabricated including functionalized multiwall carbon nanotubes by means of ...
Estudio para la optimización de la composición de un HACFRA (hormigón autocompactante reforzado con fibras de acero) estructural
(Consejo Superior de Investigaciones CIentíficas (CSIC), 2015)
El interés de un HACFRA (Hormigón autocompactante reforzado con fibras de acero), radica en la combinación del incremento de capacidad resistente con respecto al hormigón y disminución de la fisuración, aportada por la ...
Influence of the modification with MWCNT on the interlaminar fracture properties of long carbon fiber composites
(Elsevier, 2011-11-12)
This paper reports the processing of a carbon fiber reinforced epoxy composite with carbon nanotube integration and examines the potential improvement on the interlaminar toughness. Carbon nanotube enhanced composites were ...
Thermal performance of sawdust and lime-mud concrete masonry units
(Elsevier, 2018-04)
Over the past three decades, growing interest in the properties of thermal envelopes and their enhancement has led to the development of new sustainable materials. Nevertheless, Concrete Masonry Units (CMUs) with negligible ...
