The strain hardening tends to increase Strain Hardening
audi.nchu.edu.twhardening is the simple power law. • As n varies, the shape of the true stress-strain curve also alters (see figure). If n is low, the work-hardening rate is initially high but the rate decreases rapidly with strain. On the other hand, with a high n, the initial work hardening is less rapid but continues to high strains. K n
