Ultra-strength materials
Recent experiments on nanostructured materials, such as nanoparticles, nanowires, nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of ‘‘ultra-strength” phenomena, defined by stresses in a material component generally rising up to a significant fraction > 1 10 of its ideal strength – the highest achievable stress of a defect-free crystal at zero temperature. While conven...
متن کاملMechanics of Ultra - Strength Materials
167 Abstract Recent experiments on nanoscale materials, including nanowires, nanopillars, nanoparticles, nanolayers, and nanocrystals, have revealed a host of “ultra-strength” phenomena, defined by stresses in the material generally rising up to a significant fraction of the ideal strength—the highest achievable strength of a defect-free crystal. This article presents an overview of the strengt...
متن کاملAtomistic Measures of Materials Strength
We examine the role of atomistic simulations in multiscale modeling of mechanical behavior of stressed solids. Theoretical strength is defined through modes of structural instability which, in the long wavelength limit, are specified by criteria involving elastic stiffness coefficients and the applied stress; more generally, strength can be characterized by the onset of soft vibrational modes i...
متن کاملShear strength of granular materials
RÉSUMÉ. La résitance des matériaux granulaires au cisaillement est généralement attribuée à l’anisotropie de la microstructure granulaire. La question de savoir comment l’anisotropie, et donc la résistance au cisaillement, dépend des propriétés des particules, reste ouverte. Dans cet article, nous proposons d’abord une synthèse sur le rôle des anisotropies de la texture et des forces vis-à-vis ...
متن کاملStrength and Robustness of Protein Materials
The use of classes of materials has been used to classify stages of civilizations, ranging from the Stone Age more than 300,000 years ago, to the Bronze Age, and possibly the Silicon Age in the late 20th and early 21st centuries. However, a systematic analysis of materials in the context of linking chemical and physical concepts as well as the understanding and manipulation of nanostructures fo...
