铝合金工字梁腹板屈曲后承载力有限元分析中材料本构关系模型的探讨

The Discussion of Material Stress-strain Relationship Model in Finite Element Analysis of Aluminum I-beam Web Post-buckling Behavior

本文采用五种不同的铝合金本构关系模型,用有限元分析软件ANSYS对铝合金工字梁腹板屈曲后承载力进行了数值模拟,并通过对有限元计算结果和试验值的比较,分析不同材料本构关系模型对铝合金工字梁腹板屈曲后承载力计算精度的影响。

This paper introduced five aluminum alloy stress-strain models,numerical simulation of aluminum I-beam web post-buckling behavior by ANSYS software,through compared with ANSYS calculated results and the test value to discuss the calculation precision of aluminum I-beam web post-buckling behavior were affected by different stress-strain models.
