Book Description
The paper begins with a short overview of the recent work done in the field of discontinuous reinforced composites, focusing on the different parameters which influence the material behavior of discontinuous reinforced composites, as well as the various analysis approaches undertaken. Based on this overview it became evident that in order to investigate the enumerated effects in an efficient and comprehensive manner, an alternative approach to the computationally intensive finite-element based micromechanics approach is required. Therefore, an investigation is conducted to demonstrate the utility of utilizing the generalized method of cells (GMC), a semi-analytical micromechanics-based approach, to simulate the elastic and elastoplastic material behavior of aligned short fiber composites. The results are compared with simulations using other micromechanical based mean field models and finite element (FE) unit cell models found in the literature given elastic material behavior, as well as finite element unit cell and a new semianalytical elastoplastic shear lag model in the inelastic range. GMC is shown to definitely have a window of applicability when simulating discontinuously reinforced composite material behavior.Pahr, D. H. and Arnold, S.

Book Description
Summary: A Generalized Multiscale Analysis Approach brings together comprehensive background information on the multiscale nature of the composite, constituent material behaviour, damage models and key techniques for multiscale modelling, as well as presenting the findings and methods, developed over a lifetime's research, of three leading experts in the field. The unified approach presented in the book for conducting multiscale analysis and design of conventional and smart composite materials is also applicable for structures with complete linear and nonlinear material behavior, with numerous applications provided to illustrate use. Modeling composite behaviour is a key challenge in research and industry; when done efficiently and reliably it can save money, decrease time to market with new innovations and prevent component failure.

Book Description
This volume, the sixth in a continuing series, presents cutting edge multidisciplinary work on the characterization of ancient materials; the technologies of selection, production and usage by which materials are transformed into objects and artifacts; the science underlying their deterioration, preservation and conservation; and sociocultural interpretation derived from an empirical methodology of observation, measurement and experimentation. Preserving cultural heritage extends beyond artifact preservation to developing a critical understanding of how ancient people used technology and craft to solve problems of survival and organization and to make symbols or representations of what was important in their world, especially for its maintenance, longevity and beautification. Of particular interest in this volume are contributions which explore the interface and overlap among traditional materials science, the history of technology and the archaeological and conservation sciences, or that investigate new methods and applications of materials science in art and archaeology. Topics include: conservation and preservation science; preservation-design, characterization and assessment; characterization-new methods and improved techniques; archaeological science and archaeometry; site formation, site analysis, resource survey and organization of technology; weathering, dating, technology and authentication; archaeomaterials, technology and society; replicative experiments, synthesis of materials and model systems; historic technologies; and ancient technology and modern craft.
