在本研究中，利用有限元 (FE) 模拟和高能同步加速器 X 射线衍射研究了线性摩擦焊 (LFW) 件中的残余应力分布。采用全耦合隐式热机械分析模拟程序，使用Python脚本进行半自动重新网格划分以适应大变形，并输出轮廓跟踪方法以提取变形配置。利用多探测器多色同步加速器X射线实验数据验证的模型研究了线性摩擦焊件(LFW)中的残余应力分布，为描述残余应力分布提供了通用函数。在图中发现了特征长度尺度。 (c) 2013 Elsevier Ltd. 保留所有权利。
In the present study, the residual stresses distribution in the Linear Friction Welded (LFW) pieces were studied using Finite Element (FE) simulation and high energy synchrotron X-ray diffraction. Fully-coupled implicit thermo-mechanical analysis simulation procedure was employed, with semi-automatic re-meshing using Python scripting to accommodate large deformation and output contour tracking methods for extracting deformed configurations. Model validated by the multi-detector polychromatic synchrotron X-ray experimental data were used to study the distribution of residual stresses distribution in the Linear Friction Welded (LFW) pieces to provide a general function to describe the residual stresses distribution. A characteristic length scale was found in the plot. (c) 2013 Elsevier Ltd. All rights reserved.
