| Abstract: | Four currently utilized constitutive models for metals (i.e. Johnson–Cook, Zerilli–Armstrong, Bodner–Partom and Khan–Huang) are investigated and used to predict the mechanical behaviors of the materials and compared with experimental results. Limitations for each model in describing work-hardening behavior of metals are discussed. |
