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 ...
Analysis of Photodiode Monitoring in Laser Cutting
(MDPI, 2020-09-19)
The paper presents the results of an analysis based on the photodiode monitoring signals obtained during the laser cutting of aluminum and stainless steel plates. The mean level of the monitoring signal was measured and ...
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 ...
