On a plot of creep rupture stress versus duration, an inflection is observed for cross-weld specimens. This inflection occurs at a threshold stress level for a given temperature and material. (W 22) (1)

Cross-weld specimens = Espécimes de solda cruzada

Data derived from tests using deeply-cracked specimens may result in non-conservative life predictions. (W 152)  (2)

Deeply-cracked specimens = Espécimes rachados profundamente

The testing conditions in this study were very severe, and the investigators pointed out that SCC tests repeated on U-bend specimens did not reveal any susceptibility. (W 190) (3)

U-bend specimens = Espécimes um U
