Forming Limit Prediction for Nickel Coated Sheet Based on Ductile Fracture Criterion by Finite Element Method
摘 要
首先通过拉伸试验,得到了镍涂层薄钢板和低碳钢薄板的材料参数,然后利用有限元软件Abaqus/Explicit对镍涂层薄钢板的冲压成形过程进行了有限元模拟,得到了涂层和基体在冲压变形过程中的应力、应变以及断裂的初始位置及厚度分布,并通过Oyane韧性断裂准则预测了镍涂层薄钢板的成形极限;并将韧性断裂准则的理论计算、试验结果与有限元计算结果进行对比.结果表明:Oyane韧性断裂准则能够较好地预测镍涂层薄板的成形极限和失效的初始位置,预测值与试验值相差较小.
Abstract
The material parameters of nickel coated sheet and low-carbon sheet were obtained firstly by tensile tests,and then,the stamping processing was simulated by finite element software Abaqus/Explicit.From the computation,the history of stress and strain in the coating and the substrate,the fracture initiation site and the distribution of the thickness were got,and the forming limit was predicted by using the Oyane ductile fracture criterion.The computation results based on Oyane ductile fracture criteria,experimental results and FE simulation results were compared.The results show that Oyane ductile fracture criterion can preferably predict the forming limit and facture initiation site of nickel coated sheet,and only keep a small difference with the experimental results.
