stress-relaxation test

基本解釋

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.
對軟組織進(jìn)行應(yīng)力松弛試驗時可給樣本施加一個小的預(yù)加力來去除樣本的松弛，該預(yù)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.
根據(jù)ASTM E328—78設(shè)計了等應(yīng)力的片形應(yīng)力松弛測試試樣，對其應(yīng)力松弛測試裝置進(jìn)行了初步探索，并進(jìn)行了應(yīng)力松弛測試試驗研究。
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.
本文采用拉伸應(yīng)力松弛試驗，模擬R-26合金在30/60萬千瓦汽輪機用作緊固件的工作條件，研究合金在高溫不同初始應(yīng)力下，長期工作時的應(yīng)力松弛行為。
