Crystal-plasticity-finite-element modeling of the dynamic response of a directionally solidified nickel-based superalloy
(2020)
The flow stress behaviour of a directionally solidified nickel-base superalloy,MAR-M247, is presented through the combination of experiments and crystal-plasticity simulations.The experimental campaign ...
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)
This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ...
Load distribution and tooth root stress of highly crowned spherical gear couplings working at high misalignment angles
(Elsevier, 2023)
Spherical gear couplings are commonly used mechanical components to transmit power between highly misaligned rotating shafts. For that, gear couplings are manufactured with high longitudinal crowning and are usually small ...
High-Frequency Modelling of Electrical Machines for EMC Analysis
(MDPI, 2024)
The trend towards electrification in mobility has led to the increased use of silicon carbide (SiC) semiconductors. These semiconductors are more efficient but also present challenges related to electromagnetic interference ...
Study of powder densification under hydrostatic loads at high temperatures using finite element method
(Elsevier, 2020)
Many different constitutive models that describe the behaviour of metal powder during hot isostatic processes are found in literature. A quantitative comparison of these material laws shows a huge discrepancy among the ...
A multiscale material model for metallic powder compaction during hot isostatic pressing
(Elsevier, 2023)
The prediction of the distortions during Near-Net-Shape Hot Isostatic Pressing (NNS-HIP) is an intrinsic multiscale problem where the local interactions among particles determine the macroscopic distortions taking place ...
Study of Astroloy powder compaction at high temperature under hydrostatic load using finite elements
(Elsevier, 2021)
The results of existing constitutive models describing the behaviour of metal powder during compaction processes are very different. This reveals the high sensitivity of the mechanical behaviour of porous materials to the ...
