Numerical Simulation of Linear Friction Welding Based on ABAQUS Environment: Challenges and Perspectives

摘要

In order to investigate the complicated thermomechanically coupled process of linear friction welding (LFW), three different numerical methods were developed using the ABAQUS software. LFW steel and Ti-6Al-4V were calculated by using a 2D model with the explicit and implicit methods, respectively, and the calculated results were validated by experiments. In addition, a 3D model for LFW Ti-5Al-2Sn-2Zr-4Mo-4Cr was firstly acquired by using the newly developed explicit-implicit alternate method and the calculated flash seemed more like the real one. Furthermore, a few open questions and perspectives in LFW modeling are discussed and concluded.
