...) is the ratio of the line segments OB / OA ( Fig. 2 ). In Fig. 2 , it is observed that, in the presence of residual stresses, the factor of safety is reduced (i.e., O ′ B ′/ O ′ A ′ is less than OB / OA ). The United Kingdom Central Electricity Generating Board (CEGB) first proposed a failure...
