With regard to testing in air, the hydrogen loss was clearly associated with strain rate, hence with duration of test. (W 19) (1)

Strain rate = Taxa de deformação

One SLC testing strategy that was not explored in the present programme was that attempted by Takatori, who investigated the influence of displacement rate during fracture toughness testing on KIC. (W 283) (2)

Displacement rate = Taxa de deslocamento

The determination of suitable endurance or fatigue crack- growth rate data is of course dependent on ensuring that tests are carried out under appropriate environmental conditions. (W 195) (3)

Crack-growth rate = Taxa de aumento de rupturas
