Coupled models related to manufacturing simulations

Abstract: Manufacturing simulations is today on a level where a manufacturingchain can be simulated including various steps such as machining, welding, metal deposition and heat treatment. This opens up for the possibility to investigate different manufacturing routes without the high costsof experimental work. In the case of welding and metal deposition theeffect of fixtures and ordering of weld sequences can be evaluated withrespect to deformation and residual stress. If a heated tool is included ina hot forming simulation there is a possibility to find process parameters that produces the desired microstructure in the sheet metal component.The work in this thesis has focused on techniques for increased effi-ciency in the context of large and complex structures and also alleviatingthe work during model definition for metal deposition and Joule heating.
