There has been increasing interest in using what are termed 'multiscale modeling' approaches to understand the effects of composition and microstructure on mechanical behavior. It is now quite common to find publications that report on related phenomena using atomistic, microscale (dislocation dynamics) and mesoscale/continuum computer simulations. With this enhanced interest in multiscale phenomena emerges a need for experimental work that validates and challenges the predictive capabilities of modeling and simulations. This book brings together experimentalists and modelers working in common areas of interest, to exchange information and lead to more tightly coupled experimental and modeling work. Topics include: plasticity at the continuum length scale; nonlocal plastic theory and dislocation phenomena; dislocation dynamics - experiments and simulation; dislocation core properties and effects; fracture and crack propagation; dislocation interactions with interfaces and grain boundaries; and microstructural modeling for industrial metals processing.

In recent years there has been increasing interest in using what are termed 'multiscale modeling' approaches to understand the effects of composition and microstructure on mechanical behavior of materials. It is of utmost importance that these modeling efforts and simulations at the various length scales be coupled with experimental work. This 2003 volume focuses on experimentally validated multiscale modeling of ductile metals and alloys. The areas of atomistic, mesoscopic and continuum modeling are featured. Topics include: multiscale modeling of plastic deformation; dislocation phenomena at the atomistic-length scale; multiscale modeling of thin films and nanoindentation; multiscale modeling of dislocation phenomena and plastic deformation; multiscale modeling of microstructures and experiments; and models and experiments in nanostructured materials.

Annotation Beginning with a concise review of the physics and chemistry of polymers and their structure and morphology, this book goes on to describe and explain the common methods of characterizing polymers, including optical microscopy, scanning electron microscopy and transmission electron microscopy, among others. Also covered are the characterization and modification of such surface properties as adhesion, wetting, tribology, and surface thermodynamics.
