Numerical Simulation of TC4 Titanium Alloy Sheet Forming by Singly Synchronized Two-Station Laser Shocking
According to existing theory of laser shock forming, using finite element analysis software ANSYS/LS-DYNA, through the reasonable simplification and modeling, and by carefully setting up the material properties, selecting elements, meshing, applying constraints, and controlling the solving steps, a finite element model for TC4 titanium alloy sheet forming by single synchronized two-station laser shocking is established and the forming process is simulated. In the post-processing, the dynamic response curve in the forming process is drawn and the characteristics of the shock wave propagation and attenuation in the target are analyzed. By using path operation, the formed contour curve is given and the stress distribution is further studied and analyzed. The study provides reference for the investigation and application of synchronized laser shock forming.
