提出了基于代表性体积元（RVE）的多尺度冷拔珠光体钢力学行为研究策略。首先，采用基于宏观尺度的有限元模型对冷拔过程进行模拟。对模型的局部网格进行细化，得到RVE尺度单元，提取该单元的弹塑性应变并映射到RVE模型中。为了进一步研究，建立了基于晶体塑性有限元法（CPFEM）的高分辨率RVE模型，研究了珠光体的力学行为。此外，还采用了一种新的分层划分方法进行几何建模。至关重要的是，模拟的极点图形与实验结果高度一致，都明显显示出α-纤维纹理。结果表明，珠光体钢的塑性和强度是由珠光体结核之间的协调变形和铁素体与渗碳体之间的相互作用决定的。
A strategy based on representative volume element (RVE) was proposed to investigate the mechanical behavior of cold-drawn pearlitic steels at multiscale. Firstly, a finite element model based on macroscale was used to simulate the cold drawing. The partial mesh of the model was refined to obtain a RVE-scale element, and the elastic-plastic strain of this element were extracted and mapped to the RVE model. For further research, a high-resolution RVE model based on the crystal plasticity finite element method (CPFEM) was established to investigate the mechanical behavior of the pearlite. In addition, a new method of hierarchical partition was used for geometric modeling. Crucially, the simulated pole figures were in high agreement with the experimental results, both prominently showing an α-fiber texture. The final results indicated that the plasticity and strength of the pearlitic steels were determined by the coordinated deformation between pearlite nodules and the interaction between ferrite and cementite.
