Interpolation range of ABAQUS temperature dependency

[jun2016]

Hi

I am trying to make a simulation of a creep material. The time-hardening power law of creep is used, which is temperature dependent as shown below. And the temperature loading profile follows the Amplitude of a cyclic change from 298.15 up to 523.15, then low down to 233.15 and up to 523.15 again.

My question is temperature dependent creep properties are given only between 423.15 and 473.15, between which a line interpolation should be used to obtain the property parameters, but what would ABAQUS process the case in default if the temperature is less than 473.15 or higher than 473.15?

Thank you in advance if anyone could help!
