During metal plastic forming, the mechanical behavior strongly depends on the strain path. In addition, the investigation of strain path effects is demanded more and more urgently in finite element numerical calculation. Therefore, it attracts many concerns again recently. Based on the literature survey and investigating experience, the development of strain path effects was introduced in detail. Firstly, the expression of strain path was introduced, and its application and localization were analyzed. Secondly, the influence of strain path on mechanical behaviors of metal was reviewed, and the micro mechanisms were also analyzed. Then, several numerical models considering strain path effects were introduced, and the applications of strain path effects in metal forming technology were reviewed. Finally, the prospects of future research direction for strain path effects in mechanical behaviors of metal were given. |
