This volume covers a broad range of phenomena in the mechanical behavior of materials that have structures and features on the nanometer-length scales in one, two and three dimensions. Many papers focus on size effects that will impact the structural alloys of the future--how macroscopic materials can be improved with nanoscale structures. These presentations show how future alloy developments will require control of material structure through processing, and how understanding fundamental deformation mechanisms will be required to truly design new ultrahigh-strength materials (including metals, ceramics, and polymer-based composites). The deformation of small structures, where the entire material sample can be smaller than micrometers, is also addressed. Mechanical structures in MEMS and coatings in microelectronics are shown to be reaching a point where measuring the properties is as difficult as fabricating the structures. Novel and exciting techniques to measure these nanometer-sized features, from submicron posts to nanoparticles of silicon, to films deposited via atomic-layer deposition, are demonstrated. The final section of the volume compares modeling deformation with either computational or analytical methods to the experimental observations and mechanistic descriptions of deformation.
