... at the temperature of 43^oC. For the long-term compressive creep behavior, three accelerated creep test methods were used in the evaluation: stepped isothermal method (SIM), time–temperature superposition (TTS), and time–temperature–stress superposition (TTSS). The results from these three tests were...

... that the compressive strength decreases linearly with inclined angle, whereas the compressive strain increases. The long-term compressive behavior (i.e. creep) was evaluated using the stepped isothermal method (SIM) at applied stresses of 10%, 20% and 30% of the normal compressive strength. The creep strain increases...

... of long-term sustained loading (SL) tests at a fixed temperature as well as simulations of monotonic loading and sustained loading at different elevated temperatures in time-temperature superposition (TTS) and stepped isothermal method (SIM) tests. The procedures to obtain the master creep strain...
