Abstract
The material failure due to stress corrosion cracking (SCC) is widely observed phenomena in many of the industrial applications. Many-a-times it causes drastic loss to the organisation. In the present work, the study is performed to evaluate the stress corrosion cracking (SCC) behaviour of SS304. The Lemaitre damage model is widely employed to evaluate the failure or damage of the engineering materials. In the present work, the Lemaitre damage model is modified by incorporating the effect of temperature and Chloride concentration to analyse SCC by recording the initiation of cracks over a period of time. The finite element analysis is performed over a rectangular specimen of SS304 by applying tensile loading under different testing temperatures and Chloride concentrations. It is observed that with the increase in temperature and Chloride concentration the number of cracks initiated increases and the time required for crack initiation decreases. Further, it is found that the effect of temperature is prominent for the initiation of crack during SCC in comparison to the Chloride concentration within the testing range.
