Abstract:The deformation characteristics of elliptic cups were studied through simulating their deep-drawing deformation processes using rigid-plastic finite element method (FEM),and the influencewas analysed of ellipticity(a/b)on strain distribution in deformation zone and formation limit.The results showed that beeause deep-drawing workpieces and their developed views are non-ro-tary,their deep-drawing deformation is non-uniform,i.e.along the outer fringe of the deforma-tion zone,where the larger the curvature,the larger the deformation degree,and the formationlimit depends greatly on the ellipticity.

 

Key words: elliptic cups deep-drawing formation limit rigid-plastic finite element method
