本课题研究的是板料成形中的一个重要的科学技术问题,即大板料成形中的起皱问题。该项目的科学内容包括两部分:(1)了解用于钣金成形的各向异性材料的力学行为和这些材料的本构关系的发展,以及(2)研究由于起皱而导致的钣金成形不稳定性。
英文摘要
This project deals with a scientifically and technically important problem in sheet metal forming, namely the study of wrinkling in large panel forming. The scientific content of the project is comprised of two parts: (1) understanding the mechanical behavior of anistropic materials used in sheet metal forming and the development of constitutive relationship for such materials, and (2) the study of instabilities in sheet forming due to wrinkling.
