摘要

In recent studies,critical research interest exists in the thermo-mechanical analysis of the friction stir welding (FSW) process by numerical simulation.In this review,the thermo-mechanical analysis for FSW is overviewed regarding the computational approaches,the heat generation,the temperature,and the material flow behavior.Current concerns,challenges,and oppor-tunities in current studies are discussed considering the application of the thermo-mechanical analysis.Generally,larger computational scale and better computational efficiency are required to allow better spatial resolution in future analysis.The concepts and approaches demonstrated in the thermo-mechanical analysis for FSW open up quantitative prospects for the design of the FSW process.
