A bead sequence-driven deposition pattern evaluation criterion for lowering residual stresses in additive manufacturing
Sun, Li; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2021)Deposition patterns can significantly influence the distribution and magnitude of residual stress in additively manufactured parts. Time-consuming thermal-mechanical simulations and costly experimental studies are often ... -
Melting cell based compensated design method for improving dimensional accuracy of additively manufactured thin channels
Sun, Li; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)Powder-bed fusion additive manufacturing technology makes it possible to produce parts with complicated geometry and high accuracy. However, dimensional deviation caused by powder overmelting and dross formation is still ... -
A new method to estimate the residual stresses in additive manufacturing characterized by point heat source
Sun, Li; Ren, Xiaobo; He, Jianying; Olsen, Jim Stian; Pallaspuro, Sakari; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)Residual stress in additive manufacturing (AM) is one of the key challenges in terms of structural integrity and finish quality of printed components. Estimating the residual stress distribution on additively manufactured ... -
Numerical investigation of a novel pattern for reducing residual stress in additive manufacturing
Sun, Li; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)Deposition patterns can significantly affect residual stress distribution in additive manufacturing processes. In this paper, a novel deposition pattern, the S-pattern, is proposed for the additive manufacturing process. ...
