【摘要】 本文利用弹塑性误差估计模型，预示出金属成形数值模拟过程中网格细化时新网格尺寸。提出补角法修正锻件边界构形并利用三次Ｂ样条统一表达边界构形，实现了对边界细化并进而产生自适应细化网格更多还原

【Abstract】 This paper calculates the predicted sizes of new meshes using error estimators based on elastic plastic theory.Added angle method is given to modifying the current boundary which is presented by cubic B splines.The boundary is first refined and adaptive refined meshes are created.更多还原
