Thermal deformations cause the particles of granular materials to rearrange. These microstructural rearrangements alter the physical properties of granular materials, influencing their ability to transfer heat, sustain loads, and allow fluid permeation. These effects, in turn, influence the behavior of granular materials.
Within this project, state-of-the-art experimental, analytical and computational techniques are employed to advance the current understanding of the influence of thermal perturbations on the physics of granular materials as well as to assess if such perturbations can be engineered in the form of thermal treatments to tailor the properties and behavior of granular materials for engineering applications.
