  • Variation of elastic strain and plastic strain of 10 CrNiMo structural steel in the course of low cycle fatigue action were studied under six series of different axial strain range from 0.6% to 2.0% by taking smooth rounded cross-section specimens. The results indicated that elastic strain range Δεe increases slightly approximately by the rule of natural logarithm and its ratio in total strain range drops gradually by power rule with a negative exponent; plastic strain range Δεp aggrandizes linearly and its ratio in total strain range increases by quadratic polynomial rule with the enhancement of total strain range ΔεT; when ΔεT is less than 1.5%, Δεe is dominant; when ΔεT is equal to 1.5%, proportions of Δεe and Δεp are similar and both are dominant; when ΔεT is more than 1.5%, Δεe increases slowly and Δεp augments at a high speed and is a dominant factor to control the whole process of low cycle fatigue.
