strain-controlled cyclic round bar tensile tests. As a result of simulation using the parameters derived from different strain amplitudes, hysteresis loop from bigger strain amplitude can predict load versus LLD behavior more precisely. Furthermore, by performing parametric studies on Q and  3 , appropriate parameters were determined. These parameters make us simulate cyclic deformation behavior even in crack problems.
