摘要：
A series of strain-controlled fully-reversed uni-axial tension-compression Low-Cycle-Fatigue (LCF) tests are carried out on IS 2062:E250A (Fe410W-A) mild steel specimens with strain amplitudes upto +/- 1.2%, to study the cyclic in-elastic material behavior. Accordingly, parameters of Cyclic-Stress-Strain (CSS) and Basquin-CoffinManson relationships are derived using the LCF test results. Further, the calibration of Non-Linear Combined (isotropic-kinematic) Hardening Material (NLCHM) model of cyclic plasticity is illustrated based on the experimental hysteresis response data. Finally, the efficiency of the calibrated NLCHM model parameters is substantiated by accurately simulating the material response from the tests conducted, using a non-linear FE software, Abaqus.
