摘要
从等Ｋ和等δ换算的定义出发，以工程中常见的埋藏和表面裂纹为例，证明了等Ｋ和等δ换算在线弹性围内使用是正确的结论。对等Ｋ和等δ换算在弹塑性范围内应用的研究提供了一个参考，同时对等Ｋ和等δ换算能安全地用于压力容器评定也将有重要的工程意义①。
In this paper, according to the definition of equivalent K and δ conversion, implanted crack and surface crack are taken for example, the correctness of equivalent K and δ conversion used in linear elastic range is proved. A reference is furnished for equivalent K and δ conversion application study in elastic-plastic range. Meanwhile, it will have important engineering significance that equivalent K and δ conversion can safely be used for pressure vessel evalution.
