Before revision: Ludwik's equation is similar but includes the yield stress: If a material has been subjected to prior deformation (at low temperature) then the yield stress will be increased by a factor depending on the amount of prior plastic strain ε0: The constant K is structure dependent and is influenced by processing while n is a material property normally lying in the range 0.2–0.5.
After revision: La legge di Hollomon non funziona bene per piccole deformazioni e va quindi corretta:Ludwik's equation is similar but includes the yield stress: If a material has been subjected to prior deformation (at low temperature) then the yield stress will be increased by a factor depending on the amount of prior plastic strain ε0: The constant K is structure dependent and is influenced by processing while n is a material property normally lying in the range 0.2–0.5.
