Finite Element Analysis and Experiment on Drawing Characteristics through Step Drawbead
계단형 드로오비드의 인출특성에 관한 유한요소해석 및 실험
Abstract
Theoretical and experimental drawing characteristics for the step drawbead are discussed. The drawbead restraining forces and strains by the varous drawing angles are measured experimentally. Also, during the blank holding process, the strain distributions of upper and lower skins of specimens are analysed by the 2-D rigid-plastic F.E.M And the drawbead restraining forces and strain distributions for the drawn specimens by the drawing length are obtained by experiment.
