摘要
对金属塑性成形的刚塑性有限元模拟过程中的网格重新划分算法进行了系统研究。根据等参单元法中的等参转换概念,应用消去理论及技巧提出了一套比较完整的刚塑性有限元网格重新划分算法,并通过界杆形零件杯形头部镦粗成形过程模拟的实例验证了该算法的可行性。
A mesh rezoning algorithm suitable for rigid-plastic finite element simulation of theplastic metalforming is studied.A new algorithm of mesh rezone is proposed in terms of theisoparametric conversion in the isoparametric element method and the elimination method.An example of the forming simulation of the cup head of a cup-rod shaped component hasbeen used to check the feasibility of the new algorithm presented here.
