A scaling law for the dynamic strength of brittle solids
TL;DR: In this paper, a universal scaling relationship is developed that describes the dynamic compressive strength of brittle solids based on the micromechanics of the growth of cracks from populations of initial flaws, and captures the fundamental dynamics of rapidly growing and interacting cracks.

Determination of Mechanical Properties of Sand Grains by Nanoindentation
TL;DR: In this article, the authors used the nanoindentation technique with a Berkovich tip to measure the Young's modulus, hardness, and fracture toughness of individual sand grains.

TL;DR: Research in this field will likely require the development of robust databases to identify patients with ITON and follow related outcomes, in addition to both in-vivo animal and virtual human models to study the mechanisms of damage and potential therapies.
Predicting variability in the dynamic failure strength of brittle materials considering pre-existing flaws
TL;DR: In this article, the authors perform two-dimensional dynamic fracture simulations of a specimen in biaxial tension, incorporating various distributions of pre-existing micro-cracks, while modeling the discrete failure processes of crack interactions and coalescence, and predict the macroscopic variability in failure strength.

Tomography and Simulation of Microstructure Evolution of a Closed-Cell Polymer Foam in Compression
TL;DR: In this paper, the microstructural evolution of closed-cell polymethacrylimide foam was simulated in compression undergoing elastic, compaction, and densification stages.
