Multiscale Lattice Discrete Particle Modeling of Concrete: Micromechanics, Scaling, Dynamics

Description:

Over 10 billion tons of concrete are produced for the construction industry every year, making concrete the second most used substance on Earth, only surpassed by water. With such high importance as a building material, there is significant need for the ability to accurately model concrete behavior. As a quasi-brittle...

Fishnet Statistics for the Strength Distribution of Nacre-like Biomimetic and Architected Quasibrittle Materials

Description:

The staggered (or imbricated) lamellar ``brick-and-mortar" nanostructure of nacre endows nacre with strength and fracture toughness values exceeding by an order of magnitude those of the constituents, and inspires the advent of new robust biomimetic materials. While many deterministic studies clarified these advantageous features in the mean sense, a closed-form...
