Multiphysics simulation of laser-material interaction during laser powder depositon
(SPRINGER LONDON LTD, 2012)
This work reports a theoretical and numerical study of the parameters related to the process of laser powder deposition through a lateral nozzle. For this purpose, a 3D quasi-stationary finite element model was developed ...
Heat transfer model and finite element formulation for simulation of selective laser melting
(Computational Mechanics, 2018-09)
A novel approach and finite element formulation for modeling the melting, consolidation, and re-solidification process that occurs in selective laser melting additive manufacturing is presented. Two state variables are ...
Hybrid additive manufacturing for tooling applications
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12-08)
The requirements for tooling manufacturing are dimensional accuracy, surface performance, hardness, wear resistance, fatigue strength, repairability and cost. In this research, a methodology for hybrid additive manufacturing, ...
Constrição e expansão eletromagnética do arco elétrico no processo GTAW aplicada na manufatura aditiva
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2022-03-04)
The wire arc additive manufacturing process uses metallic materials to deposit the layers through melting and solidification, and that have proved to be an attractive manufacturing process for medium and large parts due ...
