Abstract

Recent experiments on nanoscale and nanostructured materials, including nanowires, nanopillars, nanoparticles, nanocrystalline, and two-dimensional (2D) materials, 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. Understanding the “ultra-strength” phenomena requires an in-depth study that integrates the nanomechanical experiment and modeling. Here we present an overview on the strength-controlling deformation mechanisms as well as the nanomechanical modeling studies for ultra-strength materials. The general concepts and principles are described, with a particular emphasis on the size, temperature, and strain-rate dependence of the ultra-strength phenomena. The chapters in this Section of the Handbook are reviewed to highlight recent progress in the nanomechanical modeling of ultra-strength materials. Perspectives on the future study of nanomechanics of materials are discussed.
