Web1.Introduction. The plastic flow characteristics of metals are usually sensitive to loading rates, which is widely acknowledged as the strain rate effect [1].Rate-dependent deformation behaviors could be described by the strain rate sensitivity (SRS) parameter m [2] as (1) m = ∂ l n (σ) ∂ l n (ε ˙) ε p l, T where σ is the flow stress and ε ˙ is the strain rate.
