Plastic mechanical analysis of drawing force based on a twin elliptical die
Applied Mathematical Modelling（2020）
摘要
•A twin elliptical die whose junction is smoothly connected is designed.•The drawing force of the twin elliptical die is the smallest compared with those based on the conical die and the single elliptical die.•A higher reduction leads to the increase of the optimal die angle at a specific friction factor.
