Structural Integrity of Additively Manufactured Components (In-TEAM TC 15)

Additive manufacturing (AM) techniques offer the potential to economically fabricate customized parts with complex geometries in a rapid design-to-manufacture cycle. However, the basic understanding of the mechanical and functional behaviour of these materials must be substantially improved at all scale levels before the benefits of this rapidly developing technology can be utilized for critical load bearing applications. This advancement requires to match different competences combining both manufacturing processes and advanced design methodologies. For airframe and ground vehicle applications, developing a better understanding of fatigue performance is the key. Due to the novelty of this technology, a very limited literature exists on the stuctural integrity of AM materials. In particular, the physical phenomena linked to fracture and fatigue crack initiation and propagation in AM materials have not been investigated properly and no standards and recommendations are available up to now. Both theoretical understanding and structural applications are especially affected by this tremendous limitation. Hence, to achieve a better understanding of the basic physics phenomena and to provide effective criteria for the design would be crucial for significant advances in automotive, aerospace, and biomedical sectors which have many key potential applications based on this process with a relevant impact on many potential end-users. These advances in knowledge will open the doors for newer designs; cleaner, lighter, and safer products; shorter lead times; and lower costs. The ambitious and challenging objectives of this Technical Committee will be achieved by building an international team having the required expertise in the field.
