Fatigue behavior of IN718 microtrusses produced via fatigue behavior of in718 microtrusses produced via

Sep 05, 2016 · The microtrusses were tested under fatigue loading and with a range of stress amplitudes and compared to IN718 dogbone specimens produced under the same conditions. The failure of the microtrusses was observed to occur at the intersection between the nodes and ligaments of the microtruss, which is in concurrence with the highest stress concentration by finite element
