Additive Manufacturing (AM) is revolutionizing the design and production of complex, high performance components across aerospace, medical, automotive, energy, and other advanced engineering sectors. However, its broader adoption in fatigue- and fracture-critical applications is hindered by the presence of inherent surface and volumetric anomalies, such as porosity, lack of fusion, and surface roughness, originating from its layer-by-layer deposition process and the very rapid solidification dynamics. This symposium aims to advance our understanding of fatigue and fracture behaviour including low cycle, high cycle, and very high cycle, and fracture behaviour in AM-produced materials and structures under a broad range of loading and environmental conditions.
