摘要
对LY12CZ铝合金材料的组合强化性能进行了测试。提出了一种基于试验的组合强化模型 ,编制了应用试验组合强化模型的弹塑性有限元程序 ,并对冷胀孔边的残余应力分布进行了计算。本文的试验组合强化模型在弹塑性有限元分析中的应用 ,对计算工程中的弹塑性问题有着实际的应用价值。
The experiment of hardenning property of LY12CZ aluminum alloy is carried out, and a combined hardenning model on the base of experiment is brought forward. With the application of combined hardenning model, a program of elastic plastic finite element analysis is edited, and applied to the analysis of cold expanded hole problem. The combined hardernning model bases on experiment, and has practical value to more effectively analyze the elastic plastic problems in engineering.
