基于有限元分析的深度塑性变形技术研究进展
Research Progress of Severe Plastic Deformation Technology Based on Finite Element Aanalysis
摘要
Abstract
It is very important to research severe plastic deformation (SPD) techniques, which can make material produce ultra-fine-grain organizations and improve the properties of the material significantly. In recent years, SPD became a hot spot in research. In this paper, principles, characters, applications and development of SPD techniques were introduced and the simulation and parameter optimization process of SPD by using the finite element method were summarized. The existing problems and development prospects of SPD were also presented.关键词
