Numerical simulation of welding process – Application in buckling analysis

Abstract

Numerical simulations make the improvement of fabrication process and welding technology. Numerical simulations make the improvement of fabrication process and welding technology possible. Using finite element method the most important information about welded specimens can be determined such as deformed shape, residual stresses or even microstructural properties like phase proportions or hardness. The current study focuses on the modelling background of welding processes and the effects of different welding parameters on residual stresses and deformations. The paper focuses on heat sources, temperature dependent material properties and the development of a thermo-mechanical analysis. The virtually fabricated specimens are further analysed to investigate the stability behaviour.
