Manufacturing Processes of Integral Blade Rotors for Turbomachinery, Processes and New Approaches
(MDPI, 2020-04-28)
Manufacturing techniques applied to turbomachinery components represent a challenge in the aeronautical sector. These components are commonly composed of high resistant super-alloys; in order to satisfy the extreme working ...
Abrasive Disc Performance in Dry-Cutting of Medium-Carbon Steel
(2020-04-19)
Abrasive-cutting processes are widely used to obtain semi-finished products from metal bars, slabs, or tubes. Thus, the abrasive cutting-off process is applied when requiring precision cutting and productivity at a moderate ...
Effects of Gravity and Non-Perpendicularity during Powder-Fed Directed Energy Deposition of Ni-Based Alloy 718 through Two Types of Coaxial Nozzle
(MDPI, 2020-04-24)
The consequences of gravity and the nozzle inclination angle in the powder-fed Directed Energy Deposition (DED) process were examined in this study. We also sought to define guidelines and manufacturing strategies, depending ...
Inspection scheduling based onreliability updating of gas turbinewelded structures
(Sage, 2019-01-28)
This article presents a novel methodology for the inspection scheduling of gas turbine welded structures, based on reliability calculations and overhaul findings. The model was based on a probabilistic crack propagation ...
Fatigue Design of Dental Implant Assemblies: A Nominal Stress Approach
(MDPI, 2020-06-03)
Fatigue is the most common mechanical failure type in dental implants. ISO 14801 standardizes fatigue testing of dental implants, providing the load-life curve which is most useful for comparing the fatigue behavior of ...
On the Use of a Simplified Slip Limit Equation to Predict Screw Self-Loosening of Dental Implants Subjected to External Cycling Loading
(MDPI, 2020-09-26)
Self-loosening of the prosthetic screws is a major mechanical problem affecting roughly 10% of dental implants, according to the literature. This phenomenon may lead to micro-movements that produce crestal bone loss, ...
Evaluating Disruptive Innovation Project Management Capabilities
(MDPI, 2020-12-22)
Firms must adapt to a business environment in constant flux. Economic and political factors and the constant interruption of new technologies force firms and organizations to change and to adapt, so that they are not left ...
Compound Formation And Microstructure Of As-Cast High Entropy Aluminums
(MDPI, 2018-03-09)
The aim of this work is to study the microstructure of four high entropy alloys (HEAs) produced by large scale vacuum die casting. Al40Cu15Mn5Ni5Si20Zn15, Al45Cu15Mn5Fe5Si5Ti5Zn20, Al35Cu5Fe5Mn5Si30V10Zr10, and ...
Optimization study of the structural HACFRA composition (Self Compacting Concrete Steel Fiber Reinforced)
(Instituto de Ciencias de la construccion Eduardo Torroja, 2015-03)
The interest of HACFRA (self compacting concrete reinforced with steel fibers), is the combination of the residual strength increase and cracking decrease compared to plain concrete by the introduction of steel fibers in ...
Research Trends in Pavement Management during the First Years of the 21st Century: A Bibliometric Analysis during the 2000–2013 Period
(MDPI, 2018-07)
A bibliometric analysis based on Scopus database was carried out to identify the global research trends related to pavement management area from 2000 to 2013, and to improve the understanding of the research topics in that ...
