Abstract


Today, multiphysics modelling of single process steps as well as modelling of entire process sequences and the subsequent in-service conditions are areas which increasingly support optimization of manufactured parts. In the present paper two different examples of modelling manufacturing processes from the viewpoint of combined materials and process modelling are presented: i) Integrated modelling of spray forming and ii) Integrated multiphyics modelling of friction stir welding. The third example describes integrated modelling applied to a failure analysis of a premature rupture of a stellite weld on a P91 valve used in a powerplant. For all three examples, the focus is put on modelling results rather than describing the models in detail. Comparison with experimental work is given in all examples for model validation as well as relevant references to the original work.
