Hierarchical materials design provides opportunities for developing engineering materials with novel architectures that are yet to achieve in traditional approach of materials processing. Ice-templating is an emerging technique in which unidirectional solidification results in unique directionally porous materials, and the resulting material morphology obtained in this process does not depend on the particular material system. Ice-templated ceramics exhibit enhanced compressive strength relative to open-cell porous ceramics with random pore orientation. Therefore, due to high specific strength and energy absorption capacity, directionally porous ice-templated ceramics are promising candidate materials for armor systems, anti-mining, impact protection, and nuclear warheads. In spite of the growing interests in ice-templated materials for structural applications, limited knowledge exists on the dynamic behavior and post-fracture inelastic response. In this presentation, we will discuss our work on understanding the uniaxial compressive response of ice-templated sintered ceramics both in the quasistatic and dynamic regimes of strain rates. We utilized ice-templated alumina ceramic as a model material system and employed SHPB to measure dynamic compressive response. A high-speed camera was employed to capture the deformation and failure characteristics. In the processed ice-templated ceramic materials, porosity, lamellar bridge density, microstructural morphology and other length-scale features were modified through the systematic variations of the intrinsic and extrinsic variables. We also utilized a custom-made setup to conduct sphere impact tests on ice-templated ceramics, and studied the response of the materials during impact using a high-speed camera as well as analyzed the recovered materials for depth of penetration and mass loss due to impact. Our present work can be useful in the design and development of mechanically robust lightweight structural materials.
