本文对金属在均匀单向与复杂应力状态下的蠕变与蠕变破坏行为及结构物蠕变下持久性发展了系统的试验与理论研究。 在试验研究中本文考虑了各种金属在恒应力与变应力下的行为,应力集中,加载方式对蠕变破坏的影响;同时还提出了材料的结构损伤的新的量测方法。 In this paper, we systematically studied the experimental and theoretical research on the creep and creep rupture behaviors of metals under uniform unidirectional and complex stress conditions and the persistence under the creep of structures. In the experimental study, this paper considered the behavior of various metals under constant stress and stress, stress concentration, the impact of loading mode on creep failure; also proposed a new measurement method of structural damage of materials.
