stress-relaxation test

基本解释

When performing a stress-relaxation test of soft tissues, a small preload is usually applied to the specimen to remove slack, and this preload is generally be neglected.
对软组织进行应力松弛试验时可给样本施加一个小的预加力来去除样本的松弛，该预加力通常被忽略。
According to ASTM E328-78, uniformly stressed plate specimen and the apparatus for stress-re-laxation testing are designed. Stress-relaxation test are carried out accordingly.
根据ASTM E328—78设计了等应力的片形应力松弛测试试样，对其应力松弛测试装置进行了初步探索，并进行了应力松弛测试试验研究。
By means of constant strain-tensile test simulating long-term service conditions, the stress-relaxation behaviour of R-26 alloy for bolts of 300/600 MW steam turbines has been studied.
本文采用拉伸应力松弛试验，模拟R-26合金在30/60万千瓦汽轮机用作紧固件的工作条件，研究合金在高温不同初始应力下，长期工作时的应力松弛行为。
