Plastic Analysis and Testing of multidirectional SFRC flag slabs
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2014-09)
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 ...
Super Abrasive Machining of Integral Rotary Components Using Grinding Flank Tools
(MDPI, 2018-01-01)
Manufacturing techniques that are applied to turbomachinery components represent a challenge in the aeronautic sector. These components require high resistant super-alloys in order to satisfy the extreme working conditions ...
Comparison of Flank Super Abrasive Machining vs. Flank Milling on Inconel® 718 Surfaces
(MDPI, 2018-09)
Thermoresistant superalloys present many challenges in terms of machinability, which leads to finding new alternatives to conventional manufacturing processes. In order to face this issue, super abrasive machining (SAM) ...
Oscillating U-Shaped Body for Underwater Piezoelectric Energy Harvester Power Optimization
(MDPI, 2019-10-30)
Vibration energy harvesting (VeH) techniques by means of intentionally designed mechanisms have been used in the last decade for frequency bandwidth improvement under excitation for adequately high-vibration amplitudes. ...
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 ...
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 ...
