三种多晶塑性建模方法：泰勒模型、自洽（SC）模型和基于晶体塑性的有限元方法（CPFEM）已主要应用于模拟镁合金的织构演化。为了考察不同方法对模拟结果的影响，对基于泰勒模型的质点模拟与基于弹塑性自洽（EPSC）模型的质点模拟进行了比较。此外，还对基于单晶方案和基于多晶方案的CPFEM进行了比较。此外，通过将 AZ31 镁合金单轴压缩期间的预测织构与实验结果进行比较，对所有配方进行了验证。
Three polycrystal plasticity modeling approaches: Taylor model, self-consistent (SC) model, and crystal plasticity based finite element method (CPFEM) have been mainly applied to simulate texture evolution of magnesium alloy. To examine the influence of different approaches on simulated results, comparisons between material point simulation based on Taylor model and that based on elastic–plastic self consistent (EPSC) model are conducted. Furthermore, comparisons between CPFEM based on single crystal scheme and that based on polycrystal scheme are also carried out. In addition, all the formulations are validated by comparing the predicted textures with experimental results during uniaxial compression for AZ31 magnesium alloy.
