Abstract
Additive manufactured parts have a high potential in weight saving for aerospace applications. In the Bavarian-funded project BayLu25 – BLANCA, the Universität der Bundeswehr München, the test house GMA, the small and medium enterprise GERG and the aircraft manufacturer Boeing are working together to investigate and develop additive manufactured load introductions into sandwich parts. Certification is taken as a basis for the developments and therefore, 3D simulation methods are used to verify and validate the structure. Current metal parts are commonly certified using the von-Mises yield criterion. The advantages in higher compression and shear allowable as well as the orthotropic behavior of additive manufactured metals are not considered. To further decrease weight and therefore save CO2, the 3D material behavior of Ti-6Al-4 V is investigated in the current project. The material characterization was done by means of a test program, in which the 3D material properties for tension, compression and shear loading were determined. Furthermore, the build orientation influence on the strength and stiffness values of the specimens was evaluated. For modeling the material behavior, the Cuntze-Bold model was adapted for metallic parts.
