Abstract
The use of Direct Ink Writing (DIW) 3D printing technology allows for the fabrication of intricate structures made of metals and ceramics. Core-shell structures for biomedical applications, made of 316L steel and sphene (CaTiSiO5) are produced by co-axial DIW and reactive sintering within the MULTIFUN3D project. Other metal-ceramic combinations are considered as well. The assessment of the overall ductility and fracture characteristics of these composites deserves specific investigations. In the present work, the indirect evaluation of the fracture characteristics is performed by combining the output of small-size (in the mm range) bending tests with the numerical simulation of the experiments.| File | Dimensione | Formato | |
