The study of true the stress-strain curve for aluminum alloy plates based on 3D-DIC
Pages: 8-13
Year: Issue:  2
Journal: Journal of University of Science and Technology of Suzhou(Engineering and Technology)

Keyword:  真实应力应变三维数字图像相关Johnson-Cook本构模型有限元分析;
Abstract: 用三维图像相关方法测量并分析了铝6061板材的真实应力应变曲线,研究了不同应变计算区域的选取对计算真实应力应变曲线的影响;分析试验数据,获得了Johnson-Cook本构模型的基本参数;用有限元分析软件对试验进行仿真分析,并与试验数据数据进行了全场对比,对比结果吻合.
