The constantcreeprate was increased and creep-resistance breaking time and creep breaking elongation were decreased with the increase of applied stress.
随施加应力的增大，纤维的恒蠕变速率增大，抗蠕变断裂时间变小，蠕变断裂伸长变小。
2
The experimental items of the tests are tension of constant strain rate, creep at constant stress, and strain controlled low cycle fatigue of constant strain rate.
实验项目有等应变率拉伸、等应力蠕变和控制应变幅的等应变率塑性循环。

The strain rate was changed stepwise several times; and stress relaxation tests and a set of creep tests were performed during otherwise monotonous loading at a constant strain rate.
