| description | As a primary failure mechanism, fatigue failure of additively manufactured metallic parts has attracted considerable attention in both aerospace and biomedical applications. According to some specific design requirements, the majority of engineering components and structures contain notches of different shapes. Due to the intensive stresses around the notches, they are prone to crack nucleation. In this research, LENS (Laser Engineered Net Shaping) technology is used to fabricate Ti-6Al-4V semi-circular notched specimens. The fatigue analyses were performed to contribute to the fundamental understanding of the mechanical/cracking behaviour of additively manufactured LENS Ti-6Al-4V specimens weakened by semi-circular notches and subject to fatigue loading. |
