Abstract

There are four stages of stress corrosion crack (SCC) such as initiation, individual SC crack propagation, many crack interaction and clusters of crack formation, and finally crack or cluster instability and dynamic growth leading to the ultimate failure. The second stage is critical in determining the lifetime of pipe. Crack Layer model is adopted in this study to predict the individual SC crack propagation kinetics and the time interval from crack initiation to instability and break through. In addition, numerical simulation of Stress Corrosion Crack Layer (SCCL) and comparison with experimental observations of SCCL propagation in various thermoplastics is presented.
