17. Finally, with the validating model, the meshsize and the undercut of the clinch joint model are considered to find out the effect of the strength of clinch joint.
18. The error of data mapping from forming simulation results to crashworthiness simulation model depends on meshsize. The bigger the meshsize is, the bigger the error.
19. The matching relation between the viscosity and the mesh size was obtained using planar approximate method and integral method in the numerical modeling of divergent detonation.
