等径弯曲通道变形(Equal Channel Angular Pressing简称ECAP)由于能直接制备块状超细晶材料而备受关注。介绍了等径弯曲通道变形(ECAP)及有限元数值模拟的基本机理,并在此基础上讨论了有限元模拟在ECAP变形中的研究及发展现状。随着ECAP的深入研究和工业化的进一步发展,有限元数值模拟必然在该领域中得到越来越广泛的应用。
Equal channel angular pressing (ECAP) is now currently focused due to its capability to fabricate bulk ultrafine-grained material. This paper introduces ECAP and the finite element simuloltion etc. , and on this foundation, discusses the present study situation of finite element simulation applied in ECAP. With the further development of ECAP' and industrialization, the finite element numerical simulation must get more and more extensive appliances in that realm.
