Temperature accelerated creep testing copper
WebDuring the 1980’s the use of accelerated creep testing at temperatures up to 400C with Time-Temperature-Superposition (TTS) was established as a safe means of predicting … WebInterrupted creep tests on copper exhibit a similar temporary softness (high creep rate) upon reloading. The fact that the strainwise dying-out time of these effects is the same in both tensile and creep tests shows that they are related.
