Multiple Sensor Monitoring of CFRP Drilling to Define Cutting Parameters Sensitivity on Surface Roughness, Cylindricity and Diameter
(MDPI, 2020-06-21)
Machining parameters affects the final quality of components made in carbon fiber reinforced plastic (CFRP) composite materials. In this framework, the work here presented aims at studying the right combination of cutting ...
Self-Tuning Algorithm for Tuneable Clamping Table for Chatter Suppression in Blade Recontouring
(MDPI, 2021-03-13)
The production and repair of blades for aerospace engines and energy turbines is a complex process due their inherently low stiffness and damping properties. The final recontouring operation is usually performed by milling ...
Effect of Land Use/Cover Changes on Urban Cool Island Phenomenon in Seville, Spain
(MDPI, 2020-06-12)
This paper analyses Seville’s surface urban heat island (SUHI) phenomenon, comparing spatial and temporal patterns of land surface temperature (LST) during July 1987, 2000 and 2017. Landsat data captured throughout three ...
A Comparison of Numerical Approaches for the Design of Mooring Systems for Wave Energy Converters
(MDPI, 2020-07-16)
This paper analyses the numerical outcome of applying three different well-known mooring design approaches to a floating wave energy converter, moored by means of four catenary lines. The approaches include: a linearized ...

Tool Wear Analysis during Ultrasonic Assisted Turning of Nimonic-90 under Dry and Wet Conditions
(MDPI, 2021-08-07)
Nickel-based superalloys are widely used in the aerospace, automotive, marine and medical sectors, owing to their high mechanical strength and corrosion resistance. However, they exhibit poor machinability due to low thermal ...
A Review on Strain Gradient Plasticity Approaches in Simulation of Manufacturing Processes
(MDPI, 2020-09-03)
Predicting the performances of a manufactured part is extremely important, especially for industries in which there is almost no room for uncertainties, such as aeronautical or automotive. Simulations performed by means ...
Corrosion Fatigue Numerical Model for Austenitic and Lean-Duplex Stainless-Steel Rebars Exposed to Marine Environments
(MDPI, 2020-09-10)
Steel rebars of structures exposed to cyclic loadings and marine environments suffer an accelerated deterioration process by corrosion fatigue, causing catastrophic failure before service life ends. Hence, stainless steel ...
