摘要：

In the present research, the relationship between the strain increment and Lode parameter was obtained by using Lode parameter and Levy-Mises equation. The quantitative relation between different strain increments was presented and the relationship between plastic deformation types and Lode parameter was demonstrated. The relations between plastic deformation types and stress states were revealed and they were applied into typical metal forming process. The strain types in the workpiece were analyzed based on the numerical visualization of the values of Lode parameter. This research reveals the important role of the Lode parameter in the analysis of metal flow behavior during metal forming process.
