Im using Ramberg Osgood equation for obtaining the stress strain input data. For this i assume that the yield stress is occuring at 0.2% of plastic strain. <\/p>\n

But i cannot input the 0.2% strain in the first row of strain strain tabular data in ansys. Because we have to enter the first row as 0, Yield Stress. <\/p>\n

So i worried that changing the first point to the 0, yield stress will deviate my ramberg osgood stress strain curve data. <\/p>\n
