Fatigue Under Thermal And Mechanical Loading Mechanisms Mechanics And Modelling

Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling

This volume contains 50 contributions presented at the symposium `Fatigue under Thermal and Mechanical Loading'. The symposium addressed the mechanisms, mechanics and modelling of thermal and thermal-mechanical load effects on conventional and advanced structural materials. The proceedings provide an update of the research efforts in thermal and thermal-mechanical fatigue. The papers cover a wide range of materials, including metallic alloys from steels to advanced superalloy single crystals, ceramics as well as composites. Topics encompass recent developments in specimen and component testing techniques, mechanisms and mechanics of inelastic deformation, crack initiation and crack growth, as well as damage modelling for life-time prediction. The book is of interest to materials scientists, mechanical engineers and design engineers involved in the design of components for use at high temperatures.

Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling

The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.
