The Weldability of Duplex Stainless-Steel in Structural Components to Withstand Corrosive Marine Environments
(MDPI, 2020-11-05)
There is still a considerable gap in the definition of the weldability of Duplex Stainless Steel (DSS). A lack of clarity that is explained by the standard specification of the maximum content of equivalent carbon that ...
A new method for locating Roman transport infrastructure
(Elsevier Masson SAS, 2020-05)
Roman cities and roads, once correctly identified, can be appropriately conserved. Moreover, the correct identification of Roman transport routes will vindicate the accuracy of recent studies on the network of Roman transport ...
A skid resistance prediction model for an entire road network
(Elsevier Ltd., 2020-11-30)
[EN]This article predicts the available minimum skid resistance in the road network of Biscay (Spain) with data collected in the summer season when friction values are at a minimum. Firstly, it was observed that pavement ...
Influence of the Geometrical Design on Ball and Crossed Roller Wire Race Bearing Behavior under Axial Load
(Elsevier, 2020-12-05)
Wire bearings are becoming popular these days in applications such as defence, robotics, medical devices or shipping industry. They provide weight and inertia reductions, good shock load and vibration absorbing capacity, ...
Friction improvement via grinding wheel texturing by dressing
(Springer, 2020-05-20)
The economic and environmental cost of friction in machinery and transport is significantly remarkable, the machine tool being one of the most affected. In this sector, the movements are fully affected by the friction ...
Numerical assessment of the analytical models used to determine flexural and shear moduli in I-Beams when the tensile and compressive moduli are different
(Elsevier, 2020-01-30)
The different compressive and tensile moduli of fibre reinforced composites have been considered in the analysis of the flexural and shear moduli of I-beams. Firstly, the neutral axis has been determined analytically and ...
Numerical assessment of an experimental procedure applied to DCB tests
(Elsevier, 2020-02)
Numerical analysis of the analytic model of an experimental procedure to determine the crack length, the compliance and the energy release rate has been developed. As a first step, bending tests at different spans have ...
Laser beam welding analytical model when using wobble strategy
(Elsevier, 2020-12-23)
This article presents a model for estimating the thermal gradient, bead geometry, and microstructure in the laser welding process when the Wobble strategy is used. This method combines the main feed motion with a secondary ...
Temperature based maximum power point tracking for photovoltaic modules
(Nature, 2020-07-27)
In this article authors propose a temperature based Maximum Power Point Tracking algorithm (MPPT). Authors show that there is an optimal current vs maximum power curve that depends on photovoltaic (PV) module temperature. ...
