| Abstract Scope |
A manufacturing driven ICME framework for short fiber reinforced ceramic matrix composites via direct ink writing is proposed. Information about both the aspect ratio and orientation of the fibers is obtained from the printing process. Given this information, representative volume elements are established to provide material properties of the composite. With the fiber orientations expressed as Euler angles, the effective mechanical and thermal material properties can be calculated and then mapped onto a global geometry for finite element analysis (FEA). The FEA model is implemented in MOOSE. The model consists of four coupled modules: phase field for damage, elasticity, heat transfer, and material twinning. The effects of short fibers’ aspect ratios and alignment orientations on material performance are discussed. |
