Estimating Failure Mechanism of Steel Specimens using Stress Corrosion-Cracking (SCC) Testing Methods: State and Development

Abstract

Stress Corrosion Cracking is cracking in the material that occurs due to a combination of tensile stress, material sensitivity, and a reactive environment. SCC can cause material failure, so the phenomenon is hazardous for human life safety. It is caused by the crack propagation mechanisms that cannot be controlled, and the failure time is unpredictable. SCC susceptible is experienced by structures operating in a reactive environment such as seawater. If the material structure is in a corrosive seawater environment and receives loads from continuous waves of seawater, the structure will experience failure caused by SCC. The dangerous effects caused by SCC are necessary to research these testing methods and standards. Previous studies have conducted SCC testing using several methods, including the U-Bend specimen, C-Ring specimen, tensile specimen, and slow strain rate testing. However, comprehensive information about these methods is still limited. Therefore, it is necessary to analyze several SCC testing methods on a laboratory scale. This paper references students and future researchers who want to study the SCC phenomenon. Besides, determining the appropriate SCC testing method helps engineers consider the materials used in the design process using more advanced technology.
