Validation of Simulation Data

It is necessary to use experimental data to confirm the validity of the simulation results before further application for analysis. This concept has been recognized widely in the CFD simulation of FSW . Some of the CFD simulations used only the temperature data to validate the simulation results [4, 21]. However, the temperature results and material flow results are weakly related. The material flow need separate validation. Recently, more and more researchers has employed the microstructural features [8, 10, 15, 22] in the weld to further support the simulation model. In addition, owing to the advanced experimental approaches [23, 24], more information on the material flow during FSW can be obtained. We expect more studies to validate the simulation results.
