Within the past decade, the emphasis of scientific research worldwide has shifted to the
study of the behavior of materials at the atomic scale of matter. The proliferation of scientists
and engineers studying matter at this length scale has led to the coining of the phrase
nanotechnology. This term can generally be taken to imply the investigation and technological
utilization of the properties of matter at length scales of one thousand nanometers or
smaller. Generally, a few thousand atoms will exist in the space of thousand nanometers.
As engineers typically study the mechanical properties of materials, the corresponding
emphasis of research in the engineering community has been on nano mechanics. The
term “nano mechanics” is typically associated with the study and characterization of the
mechanical behavior of individual atoms, atomic-scale systems and structures in response
to various types of forces and loading conditions. The specific nature of nano mechanics
research generally varies depending on the discipline of the engineer; the topic of interest
can involve the atomic-scale effect of fracture and wear on material performance, mechanical
properties of nanocomposites, atomic-scale flow and locomotion of individual biological
cells.
Regardless of the interest of the particular scientist or engineer, what is universally
agreed upon is the overall potential that nanotechnology, and particularly nano mechanics,
has for the betterment of our society, including the sectors of private industry, national
defense and homeland security. An emphasis on nanoscale entities will make our manufacturing
technologies and infrastructure more sustainable in terms of reduced energy usage
and environmental pollution. Recent advances made by the research community in this
topic have stimulated ever-broader research activities in science and engineering that are
devoted to their development and applications.
Many areas of research are rapidly advancing owing to the combined efforts of science
and engineering. In mechanics and materials, we are particularly excited with the progress
in research and education that can be achieved by combining engineering and basic sciences
through modeling and simulation together with experimentation. Owing to the combination
of constantly increasing computational power and the increased knowledge and understanding
of material behavior, multiple scale modeling methods have recently emerged as the
tool of choice to link the mechanical behavior of materials from the smallest scale of atoms
to the largest scale of structures. Multiple scale methods offer the best hope for bridging
the traditional gap that exists between experimental approach, the theoretical approach and
computational modeling for studying and understanding the behavior of materials.
