Distortion Prediction Methods for Full-sized Parts Built with L-PBF — New Paper
By Rebecca Gurk on Thursday, February 2nd, 2017
Modeling approaches have been developed to study the evolution of temperature, stress, and distortion in parts built using laser powder bed fusion (L-PBF); however, the long computational times required by these techniques limit their practical use. EWI has developed and validated several improved numerical models to address this challenge, including a layer-heating approach capable of efficiently and effectively predicting the evolution of temperature, stress, strain, and distortion in full-sized L-PBF components. EWI Principal Engineer Yu-Ping Yang has written Distortion Prediction Methods for Full-sized Parts Built with Laser Powder Bed Fusion to discuss EWI’s work in modeling distortion for L-PBF.
