EWI has recently acquired a Correlated Solutions 3D digital image correlation (DIC) system.  The system was purchased for use in the EWI Forming Center for evaluation of deformation in sheet metals to produce forming limit diagrams.  A full description of the uses of DIC in characterization of material formability is located in the following link:Read more


Distortion Prediction Methods for Full-sized Parts Built with L-PBF — New Paper

By Rebecca Gurk on Thursday, February 2nd, 2017 in Additive Manufacturing, First Time Quality, Metal 3D Printing, Modeling & Simulation, Structural Integrity. No Comments

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 ofRead more
