金属蠕变与蠕变破坏理论综述

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。

SUMMARY OF RESULTS ON THEORY OF CREEP AND CREEP RUPTURE OF METALS

The authors developed a systematic experimental and theoretical study on the behaviour of creep and creep rupture of metals under uniaxial and complex stress state, as well as on durability of constructional elements during creep.In experimental studies the authors considered the behaviour of various metals under constant and variable stresses, stress concentration, influence of way of loading on creep rupture; the authors also suggested new measuring methods of structure damage of material.
