Finite elements modeling of mechanical and acoustic properties of a ceramic metamaterial assembled by robocasting

Original language description

Finite element (FE) modeling was used for numerical simulations of mechanical performance of a periodic silicon-carbide scaffold manufactured by robocasting. The FE modeling approach enabled reliable calculation of the effective anisotropic elastic properties of the scaffold at the macroscale, as well as of the acoustic band structure indicating the metamaterial-like behavior of the material at the micro-scale. In addition, the micromechanics of the scaffold was discussed based on the outputs of the model: the mechanisms of the extremely soft shearing modes were identified and the corresponding stress concentrations arising at the contact points in the scaffold were analyzed with respect to the possible failure modes of the robocast structure.
