Abstract Scope |
Stress corrosion cracking (SCC) is a widely observed problem in many industrial applications. The SCC studies are performed to ensure the safe design of the structures under stress conditions. In the present work, a numerical study is performed to analyze the SSC behavior of the material degraded under different environmental conditions. The continuum damage mechanics approach is applied to simulate the behavior of the structures. The effect of properties degradation due to environmental conditions is incorporated using different mathematical models. The finite element simulation is performed on the plate under a stressed corrosive environment. The void initiation and propagation are simulated under different loading conditions. The time taken by the voids to grow into cracks reduces with increasing the constant load. Further, it is found that the corrosive environment adversely affects the performance of the material. |
