We investigate the emergence of isotropic linear elasticity in amorphous and polycrystalline solids via extensive numerical simulations. show that elastic properties are correlated over a finite length scale ${\ensuremath{\xi}}_{E}$, so central limit theorem dictates continuum on increasing specimen size. The stiffness matrix systems size $L>{\ensuremath{\xi}}_{E}$ is obtained, adding to pre...

Many engineering metals are polycrystalline, as such the elasticity, crystalline orientation and grain distribution cardinal factors in determining physical properties of material. The can be measured using a number different techniques by subset these (electron back scatter diffraction, spatially resolved acoustic spectroscopy). These measurements routinely deployed materials development. Howe...

A three-dimensional framework for low-cycle fatigue analysis of polycrystalline aggregates is proposed in this work. First, a cohesive law coupling plasticity and damage developed modelling cycle-by-cycle degradation material interfaces up to complete de-cohesion failure. The may model both quasi-static under increasing monotonic load cyclic loading, through coupled plasticity-damage whose acti...

The field of research in polycrystalline hexagonal boron nitride (PBN) has been enjoying extraordinary growth recently, in no small part due to the rise of graphene and the technical advancement of mass production in polycrystalline 2D materials. However, as the grain size in 2D materials can strongly affect their materials properties and the performance of their relevant devices, it is highly ...
