TL;DR: An experimental investigation of stress-driven grain boundary migration manifested as grain growth in nanocrystalline aluminum thin films indicates that shear stresses drive grain boundaries to move in a manner consistent with recent molecular dynamics simulations and theoretical predictions of coupled grain boundaries migration.

TL;DR: In this paper, a three-dimensional Voronoi model is developed to investigate the mechanical behavior of linearly elastic open cell foams and the failure surface of the foams subject to multi-axial compression is determined and is found to comply with the maximum compressive principal stress criterion.

TL;DR: In this article, a discrete element simulation scheme for pebble beds in fusion blankets is presented, where each individual piece obeying equilibrium conditions under contact forces is considered as one element.

TL;DR: In this paper, the authors present an approach for the calculation of interfacial stiffness and contact area evolution between two rough bodies exhibiting self-affine surface structures using spline assisted discretization.

TL;DR: The zeta potential shift with relative adsorbate addition revealed a nearly linear correlation of a defined surface-area-dependent parameter with the conventionally measured surface area values of the powders, demonstrating that the proposed analytical framework is applicable for the in situ surface area characterization of aqueous particulate matter.
