BACKGROUND

Master thesis work that is part of an ongoing research project focusing on exploring and developing multiscale FE models and inventing methods producing novel experimental data for model validation, i.e., temperature history measurements and synchrotron tests used to map residual stresses.
Two master thesis projects will be run in parallel, evaluating the experimental data and exploring the influence of different model assumptions on a mesoscale level to the predicted temperature and stress build-up in an AM component on a macroscale level (multiscale modelling approach).

THESIS PROJECT DESCRIPTION

This thesis project will focus on developing a macroscale FE model for PBF-LB in MSC Marc. A component-like geometry will be studied and modelled. The predicted model responses are analysed by performing a parameter study by varying different input parameters and geometrical dimensions. The results developed in a Master thesis running in parallel will be applied to compare model predictions with globally or locally calibrated inherent strain values. The component geometry studied in the project is of interest to important Swedish companies, who seek FE-model methods and predictions in their efforts to perform first-time-right printing. Experimental temperature history data and residual stresses mapped from synchrotron experiments will be available.
