Architectured Multifunctional Materials

In terms of design, multifunctional requirements are becoming the rule. While previous decades were driven by the development of new materials, this new engineering approach calls for the development of 'tailored materials'. Very often, contradictory requirements cannot be met by a single material. Fortunately, various innovative strategies are possible -associating different materials, playing with materials architectures (such as foams and truss lattices), or developing microstructural gradients. While these strategies open a whole new range of materials and properties, where structural requirements and functional properties can be combined, they also reveal additional challenges. New processes must be implemented. Appropriate constitutive equations must be developed. Interfaces must be engineered. And bioinspired hierarchical structures must be developed and modeled, to name just a few. This book brings together researchers to review recent advances and address the list of challenges. Topics include: basic concepts in architecture materials; cellular and fibrous materials; processing challenges; towards structures and multifunctional materials.

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.

This book deals with a group of architectured materials. These are hybrid materials in which the constituents (even strongly dissimilar ones) are combined in a given topology and geometry to provide otherwise conflicting properties. The hybridization presented in the book occurs at various levels - from the molecular to the macroscopic (say, sub-centimeter) ones. This monograph represents a collection of programmatic chapters, defining archimats and summarizing the results obtained by using the geometry-inspired materials design. The area of architectured or geometry-inspired materials has reached a certain level of maturity and visibility for a comprehensive presentation in book form. It is written by a group of authors who are active researchers working on various aspects of architectured materials. Through its 14 chapters, the book provides definitions and descriptions of the archetypes of architectured materials and addresses the various techniques in which they can be designed, optimized, and manufactured. It covers a broad realm of archimats, from the ones occurring in nature to those that have been engineered, and discusses a range of their possible applications. The book provides inspiring and scientifically profound, yet entertaining, reading for the materials science community and beyond.

Integrated Design of Multiscale, Multifunctional Materials and Products is the first of its type to consider not only design of materials, but concurrent design of materials and products. In other words, materials are not just selected on the basis of properties, but the composition and/or microstructure iw designed to satisfy specific ranged sets of performance requirements. This book presents the motivation for pursuing concurrent design of materials and products, thoroughly discussing the details of multiscale modeling and multilevel robust design and provides details of the design methods/strategies along with selected examples of designing material attributes for specified system performance. It is intended as a monograph to serve as a foundational reference for instructors of courses at the senior and introductory graduate level in departments of materials science and engineering, mechanical engineering, aerospace engineering and civil engineering who are interested in next generation systems-based design of materials. First of its kind to consider not only design of materials, but concurrent design of materials and products Treatment of uncertainty via robust design of materials Integrates the "materials by design approach" of Olson/Ques Tek LLC with the "materials selection" approach of Ashby/Granta Distinquishes the processes of concurrent design of materials and products as an overall systems design problem from the field of multiscale modeling Systematic mathematical algorithms and methods are introduced for robust design of materials, rather than ad hoc heuristics--it is oriented towards a true systems approach to design of materials and products

Since the early 2000s, primarily research-based projects have focused on the use of new materials such as shape-memory alloys, light-emitting diodes (LED), film-encased photovoltaic cells and thermochromic paints. These materials offer a wide range of outstanding possibilities to the construction industry through their capacity to sense and respond to external environmental stimuli. However, the advent of smart materials - multifunctional materials that are designed by chemists, physicists and biologists - pose challenges for design practices exploring such innovations. Given the rich potential of these emerging materials and technologies for architecture, I was intrigued to know: what is necessary to introduce these materials in architecture? In this thesis, I report on design strategies that involve extrinsic and intrinsic material properties. My research strategies included the use of digital design tools, physical computing and hapticintuitive workflows in order to bypass a lengthy iterative design and analysis process through rapid intuitive feedback. My research demonstrates the necessity of both a digital and physical interaction with previously little- or unused engineered advanced materials, if the use of those materials is to drive change in the overall material system. This proposition is developed and tested by practice-based research and design explorations. Centred on the idea of material-driven design processes, my research addresses the work of architects, engineers and materials scientists and locates opportunities for working together within a trans-disciplinary environment. Having direct interaction with materials and their behaviours generates an awareness of the material possibilities that enables architects to engage with engineers and materials scientists. In considering both theoretical and practical implications, my research contributes to the discussion of multifunctional materials as they emerge and their applications within architecture.

A multidisciplinary approach that explores the diverse properties, functions, and applications of nanomaterials Drawing together the many scientific and engineering disciplines underlying the development of nanomaterials, Nanoscale Multifunctional Materials provides a multidisciplinary review of the diverse properties, functions, and applications of nanomaterials. The book examines both nanoparticles, which have larger-scale equivalents, and uniquely assembled nanomaterials, which do not have larger-scale equivalents. Readers will gain a tremendous appreciation of the versatility of nanomaterials as well as an understanding of how the same nanomaterial can have several distinct applications across a broad range of fields and industries. Nanoscale Multifunctional Materials is divided into three sections: Section I, Overview, describes the scientific phenomena underlying the special properties of nanomaterials, making them desirable as novel materials and different from conventional solids. Next, readers will learn about the effect of nanomaterials on contemporary society as well as future trends in nanomaterials production and use. Section II, Processing and Analysis, explores several experimental approaches in nanomaterial fabrication and characterization as well as in theoretical approaches in modeling and simulation. Section III, Applications, offers detailed examples of nanomaterial applications in alternative energy, thermal management, environmental cleanup, water treatment, and biomedicine. Each chapter has been written by one or more leading experts in the science, engineering, and application of nanomaterials. Within each chapter, readers will find a thorough review of the current literature, with references to facilitate further investigation of individual topics. Underscoring the multidisciplinary and multifunctional characteristics of nanomaterials, this book is recommended for students and professionals in science and engineering who need a broad perspective on both the nature and application of nanomaterials. The text also sets the stage for the development of new nanomaterials and new applications.

PRICM-8 features the most prominent and largest-scale interactions in advanced materials and processing in the Pacific Rim region. The conference is unique in its intrinsic nature and architecture which crosses many traditional discipline and cultural boundaries. This is a comprehensive collection of papers from the 15 symposia presented at this event.
