Abstract: A finite element modeling strategy is developed to allow for the prediction of distortion accumulation in additive manufacturing (AM) large parts (on the order of meters). A 3D thermoelastoplastic analysis is performed ...

Abstract: The effect of substrate surface preheating on part distortion in laser cladding is investigated through the experimental results of laser deposited Ti–6Al–4V. In situ temperature and distortion measurements were used to ...

Abstract: Due to the repeated thermal cycling that occurs with the processing of each subsequent layer, the microstructure of additively manufactured parts undergoes complex changes throughout the deposition process. Understanding ...

Abstract: In this paper, we advocate for a more harmonized approach to model development for additive manufacturing (AM) processes, through classification and metamodeling that will support AM process model composability, reusability, ...
