英文摘要
Main objectives of this research is the establishment of fatigue strength evaluation based on advanced fracture mechanics approach for the large welded built up structures, which enables to evaluate not only the fatigue performance but also the integrity of the structures from the crack length estimation and the loading conditions. Especially, “Fatigue crack growth estimation subjected biaxial loading with different phase of each loading direction” and “Fatigue crack evolution of a surface crack” were highlighted as the research topics in this study. In addition, improvement of fatigue crack growth considering the fatigue crack closure was conducted to support the main research topics.
