According to the time-stress equivalence principle, the creep compliance vs. time curves at five different stress levels are determined and shifted along logarithmic time axis to get a master compliance curve at a given reference stress level.

- 運用時(shí)間－應力等效原理，可以由較高應力水平下較短時(shí)間的試驗數據，通過(guò)沿時(shí)間軸的平移得到較低應力水平下材料的長(cháng)期性能。
