Abstract:
The debate on whether the creep failure is induced by a stress threshold or a strain threshold is studied on several soils in this paper with a power law model and a normalization curve. The analysis indicates: (a) the creep failure is based on a critical strain, which is obtained with a normalization curve; (b) the time to the creep failure is very long for a low stress level or a low creep exponent; (c) for a given time to the creep failure, the strain threshold could be converted to a stress threshold, and variable stress thresholds will be calculated for different times given to the creep failure; (d) the creep behavior of various materials could be compared with the normalization curve and the power law model.
