    Creep and fatigue crack growth at elevated temperatures

  • Original language description

    Engineering investigations of creep and fatigue, frequently involving fracture problems, require practical answers from modeling based on fundamental principles. It has been realized that a model suitable at atomic level may not be appropriate to solve the subsequent difficulties encountered at the macro level. However, the use of meso-fracture mechanics (FM) modeling methods, where definite assumptions and generalizations can be made, could provide an answer in macro-engineering situations. In this paper two crack growth models are described: the first, linking the micro to macro process in creep, while the second model of fatigue crack growth enables use of meso-fracture dynamics in cyclic crack growth at a range of frequencies and temperatures.
