This extended comment is in response to the letter of Barlat (Int J Mater Form 2020) concerning our recent article (Chandola et al. (Int J Mater Form 12(6):943–954 2019)). The main issue raised is an apparent “mismatch” between some of the F.E. results presented and cup forming data of Tucker (Acta Metall 9:275-286 1961). There is no mismatch because the simulation results presented in our paper correspond to a different material than the one used by Tucker (Acta Metall 9:275-286 1961). Specifically, the F.E. results correspond to an Al-Cu single crystal for which uniaxial tension characterization data were reported in Karnop and Sachs (Z Für Phys 49:480–497 1928) and was processed differently than Tucker’s material. Furthermore, in the letter of Barlat (Int J Mater Form 2020), the scope and findings of our study are misrepresented, and all the quotations from our paper are taken out of context. Detailed responses to the issues raised by Barlat (Int J Mater Form 2020) are given.

此扩展评论是对Barlat的信函（Int J Mater形式2020）关于我们最近的文章（Chandola等人（Int J Mater形式12（6）：943–954 2019）的回应。提出的主要问题是一些有限元分析结果与塔克杯成形数据之间存在明显的“不匹配”（金属学报9：275-286 1961）。没有失配是因为我们的论文中提供的模拟结果与Tucker使用的材料对应的材料不同（Acta Metall 9：275-286 1961）。特别地，有限元结果对应于Al-Cu单晶，其在Karnop和Sachs（ZFürPhys 49：480-497 1928）中报道了单轴拉伸特性数据，并且其处理方式与Tucker的材料不同。此外，在Barlat的信（Int J Mater Form 2020）中，我们的研究范围和发现被错误地陈述了，并且本文中所有引用语均与上下文无关。给出了对Barlat提出的问题的详细答复（Int J Mater Form 2020）。
