In this study, the applicability of yield criteria and flow curve models to predict forming limit curve (FLC) via the Marciniak-Kuczynski (M-K) model is investigated for TWIP900 steel. Forming limit characteristics of TWIP900 are determined experimentally and numerically. The yield criteria of Hill48, Barlat89, YLD2000-2d, and BBC2000 are tested and compared with each other. Results indicate that the YLD2000-2d and the BBC2000 yield criteria are found to be more accurate than the other criteria. The YLD2000 criterion has the best prediction capability with the Krupskowsky flow curve while the BBC2000 model has the best prediction with the Ludwick flow curve model.

TWIP900 钢的 FLC 屈服标准和流动曲线分析

在这项研究中，通过 Marciniak-Kuczynski (MK) 模型研究了屈服标准和流动曲线模型对 TWIP900 钢预测成形极限曲线 (FLC) 的适用性。TWIP900 的成形极限特性是通过实验和数值确定的。对 Hill48、Barlat89、YLD2000-2d 和 BBC2000 的屈服标准进行了测试和相互比较。结果表明，发现 YLD2000-2d 和 BBC2000 产量标准比其他标准更准确。YLD2000 准则对 Krupskowsky 流动曲线具有最佳预测能力，而 BBC2000 模型对 Ludwick 流动曲线模型具有最佳预测能力。
