Numerical Modeling of a Ceramic Honeycomb Using an Equivalent Material Model

This work presents the effectiveness of cordierite–mullite ceramic honeycombs for stress reduction and energy absorption under a blast loading. Mullite's unique needle-like microstructure and reinforcing cordierite grains serve as a crack arrester, resulting in stable crack extension, thus making it a potential energy absorbing material. In this study, a ceramic honeycomb is modelled using an equivalent material modelling approach. The force transfer via the material is analyzed using finite element simulations in LS-Dyna, and the results are presented in terms of the section force and energy absorption. To propose the optimal performance, a parametric analysis is also performed in terms of sample thickness.
