Offers a review of the newest methodologies for the characterization and modelling of lightweight materials and structures.

»Advances in Multifunctional Lightweight Structures« offers a text that provides and in-depth analyses of the thermal, electrical and mechanical responses of multi-functional lightweight structures. The authors, noted experts on the topic, address the most recent and innovative methodologies for the characterization and modelling of lightweight materials and discuss various shell and plate theories. They present multifunctional materials and structures and offer detailed descriptions of the complex modelling of these structures.

The text is divided into three sections that demonstrate a keen understanding and awareness for multi-functional lightweight structures by taking a unique approach. The authors explore multi-disciplinary modelling and characterization alongside benchmark problems and applications, topics that are rarely approached in this field. This important book:

Offers an analyses of the thermal, electrical and mechanical responses of multi-functional lightweight structures
Covers innovative methodologies for the characterization and modelling of lightweight materials and structures
Presents a characterization of a wide variety of novel materials
Considers multifunctional novel structures with potential applications in different high-tech industries
Includes efficient and highly accurate methodologies

Written for professionals, engineers and researchers in industrial and other specialized research institutions, Advances in Multifunctional Lightweight Structures offers a much needed text to the design practices of existing engineering building services and how these methods combine with recent developments.
