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.
