Are the cohesive laws of interfaces sufficient for modelling fracture in polycrystals using the cohesive zone model? We examine this question by comparing a fully atomistic simulation of a silicon polycrystal to a finite element simulation with a similar overall geometry. The cohesive laws used in the finite element simulation are measured atomistically. We describe in detail how to convert the...

patriotism and nationalism make up the two sides of the spectrum of national attachment; but with different meanings, tendencies, and outcomes. this article, based on the current theories about national attachment, tries to study this subject from a different point of view. the main goal of this article is to explain national attachment in the context of the positive feeling of people toward th...
