The conference disseminated recent research results and promoting the interaction and collaboration amongst materials scientists, mechanical engineers and design engineers.
Many engineering components and structures used in the automotive, aerospace, power generation and many other industries experience cyclic mechanical loads at high temperature or temperature transients causing thermally induced stresses. The increase of operating temperature and thermal mechanical loading trigger the interaction with time-dependent phenomena such as creep and environmental effects (oxidation, corrosion).
A large number of metallic materials were investigated including aluminium alloys for the automotive industry, steels and cast iron for the automotive industry and materials forming, stainless steels for power plants, titanium, composites, intermetallic alloys and nickel base superalloys for aircraft industry, polymers.
Important progress was observed in testing practice for high temperature behaviour, including environment and thermo-mechanical loading as well as in observation techniques.
A large problem which was emphasized is to know precisely service loading cycles under non-isothermal conditions. This was considered critical for numerous thermal fatigue problems discussed in this conference.
The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.
Readership: Postgraduate students and researchers in materials science.

Fatigue is the main cause of failure of engineering structures and components. Making reliable fatigue predictions is highly difficult because knowledge about fatigue mechanisms in all stages of the fatigue process must be developed much further. In addition, the decreasing availability of raw materials and energy resources forces engineers to continually reduce the weight of constructions. This congress presents research results also particularly for new materials, including composites. Researchers, on the other hand, are confronted with the engineering demands. Futhermore, the overwhelming development which is presently taking place in the field of computer software and hardware dealing with fatigue problems is outlined along with the directions of future developments in all areas of fatigue.
Close to 300 fully peer-reviewed papers are published in the proceedings, including nearly 30 overview and keynote papers covering the various session topics. The proceedings should therefore serve as a comprehensive review of the fatigue field at the present state-of-the-art, suitable for scientists, engineers and students.
This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective.
