The Effect of Creep on Stress and Strain Fields nearby Crack Tip

Full Text(PDF, 645KB)

Author: Fuqiang Yang, He Xue

Abstract: Stress and strain nearby crack tip are key factors in quantitatively predicting the growth rate of stress corrosion cracking (SCC). Metals will creep in high temperature water environments, which will lead to the variation of stress and strain distribution nearby crack tip and affect the SCC growth rate. The effects of creep on the stress and strain fields nearby crack tip are studied with one inch compact tension (1T-CT) specimen by finite element method in this paper. The results indicate that the stress nearby crack tip reduces dramatically because of the action of creep, but the variation of strain and plastic zone nearby the crack tip are insignificant.

Keywords: Creep; Crack Tip; Stress; Strain; Finite Element Method
