SPH/FEM Coupled High Velocity Impact

Aluminum projectile vs aluminum plate at velocity over 1000 m/s The plate is around 100 mm in radius and impacted area, covering a radius of 50 mm, is modeled with SPH. The coupling between the SPH and the FEM is achieved with CONTACT TIED NODES TO SURFACE. The target plate has a depth of 12.7 mm and fixed boundary condition is applied at its outer perimeter. MAT015 JOHNSON COOK was used for the plate and the bullet. The properties of aluminum with this material model is available in the open literature and I have used it before in this video:    • LS-DYNA TUTORIAL 15: Shaft Torsion with Ma...   The basics on how to model with SPH in LSDYNA is available here:    • LS-DYNA TUTORIAL 3: Bird Strike Simulation   How to do the SPH/FEM coupling? Check the description in this video:    • SPH Underwater Explosion   This video is a bit long so I decided to put some background music, pardon me if my choice is not good, I have a bad taste in art. Plus, I don't know where to get free music.

Once the article is accepted, then I will be able to share the file or even make a video tutorial. But for now, you can refer to the other videos mentioned above and you will be able to make your own model!
