Design, Analysis, and Application of Architected Ferroelectric Lattice Materials
Ferroelectric materials have been an area of keen interest for researchers due to their useful electro-mechanical coupling properties for a range of modern applications, such as sensing, precision actuation, or energy harvesting. The distribution of the piezoelectric coefficients, which corresponds …

Influence of geometric parameters on 3D periodic lattice effective properties
Lattice materials are generated by tessellating a unit cell, composed of a specific truss configurations, in an infinite periodicity to combine the effect of bulk material properties and geometric periodicity. They offer enhanced mechanical and dynamic properties per unit mass, and the ability to …

The quasi-static and dynamic responses of metallic sandwich structures
Lattice materials are used as the core of sandwich panels to construct light and strong structures. This thesis focuses on metallic sandwich structures and has two main objectives: (i) explore how a surface treatment can improve the strength of a lattice material and (ii) investigate the collapse …

Magnetic and Structural Instabilities in Cerium Diantimonides under Pressure
… CeSb₂ and CeAgSb₂ are closely related Kondo lattice materials that are ferromagnetic at ambient pressure, unlike the majority of magnetic cerium compounds. The application of hydrostatic pressure is commonly employed to discover new phases, by continuously tuning a magnetic state, in the …
