The objective of this study was to analyze the square cup stretching process by using the dynamic explicit finite element analytical program, which was based on the Updated Lagrangian Formulation and elasto-plastic theory. Simulation results included the deformation and crack propagation history, the variation of the work piece thickness, the Forming Limit Diagram, and the relationship between punch load and punch stroke. A set of tools was designed for the square-cup stretching experiment to verify the reliability of the program.

中文摘要本文采用显性动态有限元素法，结合材料弹塑性理论，发展出一套三维增量型之有限元素分析程式，进行金属板材方杯拉伸成形制程及破裂之分析，并探讨方杯拉伸成形历程及裂纹成长历程、工件厚度变化、成形极限图(Forming Limit Diagram， FLD)，及冲头负荷与冲程关系，并设计一组方形冲模来进行方杯拉伸成形实验，以验证程式的可信度。
