WebIn primary, or transient, creep, the strain rate is a function of time. In Class M materials, which include most pure materials, strain rate decreases over time. This can be due to … WebPopular answers (1) Strain to failure gives the measure of how much the specimen is elongated to failure. By this it means that, it you have strain to failure of 3% measured in specimen of length ...
WebThe proof stress increased linearly as the strain rate increased from 2.1×10 −4 to 2.1×10 −1 s −1 in the temperature range from 77 to 298 K. Above 298 K, however, variation of the proof stress due to the increase of the strain rate was not so evident as that observed below the room temperature. WebTherefore, tendons at low strain rates tend to absorb more mechanical energy but are less effective in carrying mechanical loads. However, tendons become stiffer and more effective in transmitting large muscular loads to …
