Measuring and Predicting the Effects of Residual Stresses from Full-Field Data in Laser-Directed Energy Deposition
This article presents a novel approach for assessing the effects of residual stresses in laser-directed energy deposition (L‑DED), the thermal expansion coefficient of thin-wall L‑DED steel specimens is measured and then used to predict the displacement fields around the drilling hole in incremental hole-drilling tests. The incremental hole-drilling test is performed on cubic L‑DED steel specimens and the displacement fields are visualized using a 3D micro-digital image correlation setup.
