On preventing the dripping effect of overhang constraints in topology optimization for additive manufacturing
(Springer, 2021-09-14)
This article falls within the scope of topology optimization for Additive Manufacturing processes and proposes an alternative strategy to prevent the phenomenon known as the Dripping Effect. The Dripping Effect is when an ...
A novel python-based floating offshore wind turbine simulation framework
(Elsevier, 2024-02)
The expansion of floating offshore wind brings the industry closer to achieving commercial viability. However, the challenging environment characterised by strong winds, waves, and currents, along with the growing size of ...
Digital Twin of the laser-DED process based on a multiscale approach
(Elsevier, 2024-04)
The ramp-up of new geometries, process parameters, and materials can be enormously time and cost-intensive in Additive Manufacturing. Especially for Laser-Directed Energy Deposition (DED-L), the extreme physical environment ...
Influence of V concentration in TiAlSiVN coating on self-lubrication, friction and tool wear during two-pass dry turning of austenitic steel 316 L
(Elsevier, 2024-05)
The present work investigates the performance of TiAlSiVN coating with 5 and 11 at% of V concentration deposited on the Al2O3/SiC cutting tools during dry turning of austenitic 316 L stainless steel. The maximum flank wear ...
Stiffening near-net-shape functional parts of Inconel 718 LPBF considering material anisotropy and subsequent machining issues
(Elsevier, 2021-12-24)
[EN] Additive manufacturing of metallic parts has witnessed significant development. The laser powder bed fusion (LPBF) process has emerged as a key process for manufacturing thin-walled components. However, despite the ...
Accurate Measurement of Temperatures in Industrial Grinding Operations with Steep Gradients
(MDPI, 2024-03-07)
Due to the continuously growing demands from high-added-value sectors such as aerospace, e-mobility or biomedical bound-abrasive technologies are the key to achieving extreme requirements. During grinding, energy is rapidly ...
CFD modelling of the powder segregation in multi-material laser directed energy deposition
(Elsevier, 2024-04)
One of the prevailing challenges in multi-material laser Directed Energy Deposition is the segregation of the constituents during the delivery of the feedstock into the melt pool. This phenomenon is of particular concern ...
Analysis of the static and dynamic elastic moduli of a one-coat rendering mortar with laboratory and in situ samples
(Elsevier, 2024-07)
Although the compressive strength is the most commonly used property to characterize mortars, it has limited representativeness in real-world applications. The deformation properties of mortars, specifically the elastic ...
In-Process Machining Distortion Prediction Method Based on Bulk Residual Stresses Estimation from Reduced Layer Removal
(MDPI, 2024-01-03)
Manufacturing structural monolithic components for the aerospace market often involves machining distortion, which entails high costs and material and energy waste in industry. Despite the development of distortion calculation ...
Fatigue Life Estimation Model of Repaired Components with the Expanded Stop-Hole Technique
(MDPI, 2024-02-01)
Fatigue crack growth tests are conducted to assess the efficacy of the stop-hole crack repair method. This straightforward and widely adopted technique involves drilling a hole at the crack tip and subsequently enlarging ...
