Fracture Analysis of Slow Strain Rate Test for Stress Corrosion Cracking

Slow-Strain-Rate (SSR) tests are usually limited to comparative evaluations of Stress Corrosion Cracking (SCC) based on relative changes in ductility parameters such as elongation and reduction in area. Recently Crack Growth Rate (CGR) and KISCC analyses of data from SSR tests have been used for SCC evaluation. Benefits of this approach are that the results can be used to develop a detailed engineering analysis.  This methodology will be discussed and the results from laboratory tests will be presented.
