Description
WIT Press High Performance Structures and Materials 2008 Edition by W. P. de Wilde, C. A. Brebbia
Most high performance structures require the development of a generation of new materials, which can more easily resist a range of external stimuli or react in a non-conventional manner. The use of novel materials and new structural concepts nowadays is not restricted to highly technical areas like aerospace, aeronautical applications or the automotive industry, but also effects fields such as civil engineering and architecture, as reflected in the diversity of topics covered in this proceedings.This book contains the papers presented at the Fourth International Conference on High Performance Structures and Materials, arranged into the following subject areas: damage and fracture mechanics; composite materials and structures; optimal design; adhesion and adhesives; natural fibre composites; behaviour of frp structures; material characterization; high performance materials; high performance concretes; reliability of structures; polymers in engineering; emerging technologies; structural characterization; structural dynamics and impact behaviour; cellular structures; health monitoring; smart and functional materials; eco-materials; fire resistant materials; and biomimetic structures and materials.Within the subject areas above, particular emphasis has been placed on intelligent structures and materials as well as the application of computational methods for their modelling, control and management. This book should be of interest to civil, mechanical, aerospace, ocean and biomedical engineers, as well as those involved in structural and material research.
