coursera 课程总结：使用 Abaqus 模拟激光焊接 本课程旨在帮助您掌握使用 Abaqus 软件进行激光焊接过程模拟。您将学习如何开发有限元模型，以研究激光焊接过程中的力学和热分布，并学会编写 Dflux 子程序。通过本课程，您将能够确定工艺参数对激光焊接的影响。 **课程内容概述：** * **激光焊接简介：** 激光焊接是一种非接触式焊接工艺，仅需从工件一侧即可进行。激光束快速加热材料（通常以毫秒计）形成焊缝，适用于狭窄区域的焊接。激光焊接根据热强度可分为传导焊和键合焊（Keyhole）。较低的功率密度会导致穿透较浅，类似于在较厚板上添加一层材料，这被称为传导焊。较高的功率密度会使部分材料蒸发，产生反压，从而增加焊缝深度并塑造焊缝形状，形成键合焊。键合焊能够实现部分或完全穿透的焊缝。 * **Abaqus 问题描述与模拟：** 本课程将详细讲解使用 Abaqus 软件进行激光焊接模拟的所有必要步骤。本研究基于现有的文献资料，对研究人员具有高度参考价值。 * **结果与结论：** 课程将重点分析残余应力和温度分布。您可以根据自身需求定制模型，并根据您的具体需求和假设进行设置。通过使用定义好的函数，您可以更清晰地了解您的模拟目标。
Aim of this Course is:Understand laser welding process simulation using Abaqus.To study the mechanical and thermal distribution on laser joining by developing a finite element model.Learn how to write subroutine Dflux code.To determine the effect of process parameter on laser joining.Introduction to laser welding:Laser is a non-contact process that requires access to the weld zone from one side of the parts being welded and the weld is formed as the intense laser light rapidly heats the material-typically calculated in milli-seconds. In addition the laser is able to weld into areas with limited access weld joint.Laser welding process can be divided in two modes, keyhole, and conduction. The mode is depending on the intensity of the heat. Thinner power densities result in weaker penetration and will act like adding upper material to a thicker plate. This issue is called conduction welding. A denser power distribution will vaporize a few of the material and hence introduce a drawback pressure which can increase the depth and shape the bead as a keyhole. Owing to the unique properties of this mode, partial and completely penetrated welds can be doneProblem Description using AbaqusI will illustrate all you need regards to Laser welding using Abaqus softwareThis study follow literature review date and very informative for researchers.Results & Conclusions.I will observe Residual stress, Temperature distribution field.We can use our own models according to our needs.We can specify our needs and assumptions.Use defined function gives more idea what you're going to do.
