Assessment and Prediction of Stress Relaxation Cracking
Status: Completed
Date Announced: July, 2018
Project reference: 33528
| Stress relaxation cracking (SRC) is a high-temperature failure mode that has plagued refineries and power-plants over a number of decades. Although some advice exists on how to mitigate against the failure mode, there have been instances where failures have occurred despite following all advice and best practice. SRC failures are generally catastrophic and might have severe cost consequences, as well as personnel health and safety implications. There is therefore a need to develop methodologies to assess and predict cracking, allowing judgements to be made as to whether components are fit for service.
