有限元法是模拟金属轧制等工业成形过程的有力工具。有限元允许用户估计轧制过程中金属板的应力分布。然而，由于模型复杂性和计算时间，FE模拟不允许实时在线过程控制。本文是一个大规模研究项目的一部分，该项目旨在设计一个简单但准确的数学模型，该模型提供足够精确的结果（与FE模拟相比），具有更快的计算时间尺度，允许实时过程控制。为了验证基于渐近的数学模型，需要精确的有限元模型。在本文中，我们给出了一个准静态Abaqus/显式有限元模型的详细描述，并展示了如何优化，以代表轧制过程。我们报告了从FE模拟中获得的新见解，这些新见解可以指导更简单，更快的数学模型的开发。
The finite element (FE) method is a powerful tool for simulating industrial metal forming processes such as metal rolling. FE allows users to estimate the stress distribution in the metal sheet during the rolling process. However, FE simulations do not allow for real-time online process control due to model complexity and computational time. This paper forms part of a large-scale research project aimed at designing a simple-but-accurate mathematical model that provides sufficiently precise results (compared to FE simulations) with faster computational timescales allowing for real-time process control. To validate the asympotics-based mathematical model, an accurate FE model is required. In this paper, we give a detailed description of a quasi-static Abaqus/Explicit FE model and show how this is optimised to represent the rolling process. We report new insights gained from the FE simulations which can guide the development of simpler, faster mathematical models.
