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) ...
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 ...
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 ...
Analysis of DCB test of angle-ply laminates including bending-twisting coupling
(Elsevier, 2018-02-13)
Se analiza la fractura interlaminar de laminados simétricos y antisimétricos angulares mediante el método Double Cantilever Beam. Como los semi-laminados son simétricos en ambos casos, se produce un acoplamiento de ...
A study on the durability of structural concrete incorporating electric steelmaking slag
(Elsevier, 2018-02-10)
The durability of structural concrete mixes prepared with electric steelmaking aggregates is tested for use in normal and aggressive environments. Samples of “pumpable” and “self-compacting” concrete mixes are shown to ...
An engineering approach for the estimation of slewing bearing stiffness in Wind Turbine Generators
(Wiley, 2018-11-30)
The stiffness of yaw and pitch slewing bearings has a critical influence on the structural
behaviour of Wind Turbine Generators. Thus, it is commonly required by designers for
their simulations to estimate deformations ...
Efficient assembly of bolted joints under external loads using numerical FEM
(Elsevier, 2018-05-16)
Several factors can cause leakages in a bolted flange connection, external loads being the
most important one. External loads such as those produced by misalignment introduce an
external axial load combined with a bending ...
Effect of microwave heating damage on the electrical, thermal and mechanical properties of fibre-reinforced cement mortars
(Elsevier, 2018)
Nowadays, refurbishing of existing structures has gained interest in order to reduce both the construction materials used and the construction and demolition waste production. For that purpose, there are several methods ...
Bonding strength of stainless steel rebars in concretes exposed to marine environments
(Elsevier, 2018-05-30)
[EN] Many studies have corroborated the use of Stainless Steel Reinforcements (SSR) for structures in corrosive environments. However, even though the conditions for their employment are specified in different standards, ...
