SEMINAR ABSTRACT:
Additive manufacturing is a rapidly growing technology allowing great design freedom compared to conventional manufacturing methods. However, despite marked progress, there is still lack of knowledge and experimental data revealing the damage mechanisms in complex loading conditions. The speaker’s work is focused on an experimental study of the damage-to-failure mechanism of additively manufactured 316L stainless steel specimens subjected to very high cycle fatigue (VHCF) loading. The results of the ultrasonic axial tension-compression tests on specimens up to 109 cycles will be presented.
Moreover, the possibility of using artificially created defects for studying the VHCF behavior of additively manufactured specimens will be discussed.
