Friction Stir Welding (FSW) is a solid-state joining process that has several benefits over conventional welding techniques. A major challenge is its high sensitivity to process parameters such as advancing and rotational speed. Simulations are a key tool for understanding the material flow and temperature evolution and help to find the best processing parameters for a given FSW task. This work proposes using the Embedded Domain Method (EDM) for the simulation of FSW to overcome the limitations of (purely) Lagrangian, Eulerian, or Arbitrary Lagrangian Eulerian (ALE) approaches.

用于增强搅拌摩擦焊工艺建模的嵌入式技术


搅拌摩擦焊 （FSW） 是一种固态连接工艺，与传统焊接技术相比具有多项优势。一个主要挑战是它对工艺参数（如前进和转速）的高度敏感。模拟是了解物料流动和温度演变的关键工具，有助于为给定的 FSW 任务找到最佳加工参数。这项工作建议使用嵌入式域方法 （EDM） 来模拟 FSW，以克服（纯）拉格朗日、欧拉或任意拉格朗日欧拉 （ALE） 方法的局限性。
