AZ31B镁合金板料超塑性成形极限数值模拟

摘要

In the process of superplastic deformation of AZ31B magnesium alloy ,the damage impact should be considered .In this paper ,the basic equation of forming limit is established .T he theoretical pre‐diction is done with the numerical simulation program ,and its results are verified by experiments .%A Z31B镁合金在超塑性变形过程中需考虑损伤效应的影响，文章通过建立其成形极限的基本方程，运用数值模拟程序对其成形极限进行理论预测，并由实验对理论预测结果进行了验证。
