Reduction of Die Wear and Structural Defects of Railway Screw Spike Heads Estimated by FEM
(MDPI, 2021-11-15)
Railway spike screws are manufactured by hot forging on a massive scale, due to each kilometer of railway track needing 8600 spike screws. These components have a low market value, so the head must be formed in a single ...
On the Relationship between Mechanical Properties and Crystallisation of Chemically Post-Processed Additive Manufactured Polylactic Acid Pieces
(MDPI, 2020-04-18)
Nowadays, improvement of the surface finish of parts manufactured by fused deposition modelling is a well-studied topic. Chemical post-treatments have proven to be the best technique in terms of time consumption and ...
Requirements and Solutions for Motion Limb Assistance of COVID-19 Patients
(MDPI, 2022)
COVID-19 patients are strongly affected in terms of limb motion when imbedded during the acute phase of the infection, but also during the course of recovery therapies. Peculiarities are investigated for design requirements ...
The effect of preforming and infusing bindered and unbindered carbon non-crimp-fabrics on the final quality of composites parts
(Elsevier, 2022)
[EN] Vacuum infusion (VI) is a liquid moulding process used to manufacture fibre-reinforced polymer composite parts. The VI process for non-crimp fabric (NCF) preforms is one of the most promising processes for improving ...

(MDPI, 2021-12-15)
Machining of Titanium alloys (Ti6Al4V) becomes more vital due to its essential role in biomedical, aerospace, and many other industries owing to the enhanced engineering properties. In the current study, a Box–Behnken ...
Numerical Modeling of the Influence of Nanometric Ceramic Particles on the Nucleation of AlSi10MnMg Alloy
(MDPI, 2022-05-17)
In recent years, many researchers have attempted to model the solidification process of nano-reinforced materials. In the present document, the effect on the heterogeneous solidification regime of the different sizes, ...
Effect of WEDM Process Parameters on Surface Morphology of Nitinol Shape Memory Alloy
(MDPI, 2020-11-03)
Nickel–titanium shape memory alloys (SMAs) have started becoming popular owing to their unique ability to memorize or regain their original shape from the plastically deformed condition by means of heating or magnetic or ...
Tool Wear Effect on Surface Integrity in AISI 1045 Steel Dry Turning
(MDPI, 2022-03-09)
In the present work, the surface integrity and flank wear of uncoated cermet inserts in dry turning of AISI 1045 steel were evaluated. Three-dimensional techniques were used to assess the surface roughness. Previously, ...
Effect of the geometry of butt-joint implant-supported restorations on the fatigue life of prosthetic screws.
(Elsevier, 2022-03)
[EN] STATEMENT OF PROBLEM: Dental implant geometry affects the mechanical performance and fatigue behavior of butt-joint implant-supported restorations. However, failure of the implant component has been generally studied ...
