对设备和零件的内应力程度的了解是决定产品的质量、寿命以及安全性和可靠性的一个重要因素。 无损应力检测技术可以用来对设备的安全性、寿命和评定零件完整性提供定量检查。设在Harwell实验室的国家NDT(无损检测)中心研究出一种综合方法来确定残余应力。这种方法是各种技术独特的组合,可用于制造厂或设备现场。 Knowledge of the degree of internal stress in equipment and parts is an important factor in determining product quality, longevity and safety and reliability. Non-destructive stress detection technology can be used to provide a quantitative check on equipment safety, lifetime and component integrity. The NDT (Nondestructive Testing) Center at Harwell Laboratories has developed an integrated approach to determine residual stress. This method is a unique combination of various technologies and can be used at the manufacturing plant or at the equipment site.
