汽轮机转子中缺陷 裂纹的线弹性断裂问题

Problems of Linear Elastic Rupture of Defects and Flaws in Turbo-rotor

本文针对汽轮机转子中受热应力作用的不同类型的缺陷或裂纹,用有效应力法给出了缺陷或裂纹的应力强度因子的线弹性近似解,并就其在工程中的使用问题作了进一步的讨论.

For various types of defects and flaws resulted from heat stress in the turbo-rotor,this paper proposes a elastic approximate solution of strength factor of stress of the defects and flaws by effective stress method, and further discusses its application in engineering.
