- 論文の詳細を見る
High-temperature structural components such as pressure vessels and pipes in nuclear reactors and chemical plants, are subjected to repeated loading due to the changes of internal pressure and temperature etc.. In recent years, it has become more important to perform more accurate theoretical analysis of mechanical behaviors of the above structures for rational design and for critical evaluation of safety. In this study, the thermal elastic-plastic creep theory represented by the authors will be further developed by introducing more general forms of workhardening rule and creep law respectively.
