Abstract: The
research and development survey of finite element models in springback
numerical simulation of sheet metal forming is reviewed. The finite
element models used in springback analysis in engineering at present and
their characteristics are explained and compared with each other. The
research and development status of the new element models- incompatible
modes used in nonlinear finite element analysis at present are
introduced, and the international research hot topic and development
trend in this field are pointed out.
Key
words: Finite
