The interest of HACFRA (self compacting concrete reinforced with steel fibers), is the combination of the residual strength increase and cracking decrease compared to plain concrete by the introduction of steel fibers in ...

Artezketan eragiten duten fenomenoak, harriaren eta piezaren arteko kontaktu-baldintzen naturarekin eta horien bilakaerarekin lotura zuzena dute. Kontaktu-eremuaren definizioak funtsezko garrantzia dauka artezketa-tenperaturen, ...

El objetivo de la presente tesis doctoral es profundizar en el conocimiento del comportamiento biomecánico de los implantes dentales, las estructuras sobre implantes dentales y los microimplantes utilizados tanto como ...

This paper presents a theoretical and experimental study of multidirectional steel fibers reinforced concrete slabs (SFRC). The study is based on a real building application using SFRC flag slabs. For the evaluation of the ...

Grinding is an advanced machining process for the manufacturing of valuable complex and accurate parts for high added value sectors such as aerospace, wind generation, etc. Due to the extremely severe conditions inside ...

Scanning electron microscopy (SEM) has been used to identify and analyse the secondary adhesion effect precursors formed during the dry drilling processes of Ti-6Al-4V alloy over the rake face and flute of the drilling ...

The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track ...

This study developed a framework for the shape optimization of aerodynamics profiles using computational fluid dynamics (CFD) and genetic algorithms. Agenetic algorithm code and a commercial CFD code were integrated to ...
