“…The models revealed information about the distribution of temperature and residual stresses, as well as the overall distortion [6,27,28]. Zielinski [29] utilized a numerical model to investigate the distortion evolution of a bridge geometry part produced using an SLM process. He found that the newly deposited metal layers could dramatically transform the distortion distribution of previous deposited metal structures.…”

Assumption of Constraining Force to Explain Distortion in Laser Additive Manufacturing

Distortion is a common but unrevealed problem in metal additive manufacturing, due to the rapid melting in metallurgy and the intricate thermal-mechanical processes involved. We explain the distortion mechanism and major influencing factors by assumption of constraining force, which is assumed between the added layer and substrate. The constraining force was set to act on the substrate in a static structural finite element analysis (FEA) model. The results were compared with those of a thermal-mechanical FEA model and experiments. The constraining force and the associated static structural FEA showed trends in distortion and stress distribution similar to those shown by thermal-mechanical FEA and experiments. It can be concluded that the constraining force acting on the substrate is a major contributory factor towards the distortion mechanism. The constraining force seems to be primarily related to the material properties, temperature, and cross-sectional area of the added layer.

“…A meaningful modelling of spattering during melting and solidification in LPBF processes requires the resolution of the phenomena down to the powder particle scale. In the meantime, various simulation frameworks have been developed by various groups in recent years to model LPBF and related processes based on a continuum mechanical approach [10][11][12][13][14][15][16][17]. A comprehensive review of simulation of melt pool behaviour during AM is given by Cook et al [18].…”
