Full Description
Offers a review of the newest methodologies for the characterization and modelling of lightweight materials and structures
Advanced Multifunctional Lightweight Aerostructures provides an in-depth analysis 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 multiscale simulation approaches and nonlinear/structural dynamics methodologies. They present multifunctional materials and structures and offer detailed descriptions of the complex modelling of these structures.
The authors divide the text into two sections and demonstrate a keen understanding and awareness of multi-functional lightweight aerostructures by taking unique approaches. They explore multi-disciplinary modelling and characterization alongside benchmark problems and applications, topics that are rarely approached in this field. This important book:
Offers thermal, electrical, and mechanical analyses of multi-functional lightweight structures
Covers innovative methodologies for the characterization and modelling of lightweight materials and structures
Presents characterizations of a wide variety of novel materials
Considers multifunctional novel structures with potential applications in different high-tech industries
Discusses thermal and mechanical behaviors of some critical parts of aircrafts
Includes efficient and highly accurate methodologies
Written for professionals, engineers, researchers, and educators in academia, industrial, and other specialized research institutions, Advanced Multifunctional Lightweight Aerostructures is a much-needed text on the design practices of existing engineering building services and how these methods combine with recent developments.
