| Abstract Scope |
Due to benefits such as feasibility of complex geometries, timescales, materials savings, additive manufacturing technologies have been increasingly considered for a variety of applications in the automotive, aerospace, and defense industries. While extensive efforts have been devoted over the past two decades, the focus has been mainly on gaining understanding of the microstructures that develop and establishing a set of optimized processing conditions or parameters to ensure control/predictability of the respective microstructures. However, in view of certification engineering scale models applicable to general, multiaxial loadings are needed. In this talk, we show that an elasto-plastic macroscopic model involving a few parameters which are expressible in terms of mechanical properties measurable in simple tension and compression tests, can lead to accurate predictions of the mechanical response in shear Illustrative examples are presented for EBM Ti6AL4V and LPBF 316Lsteel. |
