i have query regarding what values should i input in yield stress and strain of steel , when i know that yield stress of steel 333MPA then the initial yield stress value what i need to give ? and while giving this value i.e 333 how much strain should i provide . Data with me which i have is transverse and axial strain (steel yield strains)and corresponding to it the axial load. do i need to give any other property as i am performing the axial compressive test on it.
