Life prediction Is usually based on the secondary creep path until the onset of tertiary creep.
Since MOPE is an isotropic volumetrically stable material for which the secondary creep path is known to be established within days [29], semi-logarithmic techniques can be used [30] to extrapolate the above behavior prior to the onset of tertiary creep.
Last, the tertiary creep occurs when a dramatic increase in creep rate is followed by an eventual rupture.
No tertiary creep was observed, even for the highest stress level of 25.
