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. ...
