bilinear isotropic hardening

是翻译成 双线性等向性硬化 吗?

为何 双线性等向强化 跟 切变模数.降伏强度 有关联性?

你看一下弹塑性分析中的硬化法则就知道了

Bilinear Isotropic Hardening Material Model. The Bilinear Isotropic Hardening (TB,BISO) option uses the von Mises yield criteria coupled with an isotropic work hardening assumption. This option is often preferred for large strain analyses. You can combine BISO with Chaboche, creep, viscoplastic, and Hill anisotropy options to simulate more complex material behaviors. See Material Model Combinations in the Element Reference for the combination possibilities. Also, see Material Model Combination Examples in this chapter for sample input listings of material combinations.

你能把 Chaboche，蠕变(creep)，粘塑性(viscoplastic) 和 希尔异向性(Hill anisotropy) 的选项

与BISO组合起来模拟更复杂的材料性能。

Chaboche 是什么 ?
希尔异向性(Hill anisotropy) 是什么 ?
所有的异向性都通称为 希尔异向性(Hill anisotropy) 吗?

这是一些力学本构模型，建议去系统学一下粘塑性力学吧
