金属薄板成形性能与试验方法成形极限图 - This paper overviewed the prediction methods of forming limit in sheet metal forming , which included forming limit stress diagram , the maximum forming thinning ratio , forming limit diagram and ductile fracture criteria ( dfc )
摘要对板料成形中的成形极限应力图、最大变薄率、成形极限图以及韧性断裂准则等预测成形极限的方法，进行了综述和分析。 - The finite element numerical simulation analysis is an important method to predict sheet metal instability in the sheet metal forming process . and the current general - purpose finite element codes all choose the strain - based forming limit diagram as the instability criterion , which has the limitation of correlative to the strain path . thus it is very inconvenient to study sheet metal forming under complex strain paths
有限元模拟是板料成形过程中预测板料失稳的重要手段,考虑到当前通用的有限元软件都是以存在应变路径相关性缺陷的基于应变的成形极限图为失稳判据,以致在研究复杂应变路径板成形时极为不便。
